Product Description
Premium Screw-Cap Sample Bottles – Where Luxury Meets Practicality for Your Brand
About This Product
We started making these bottles after a conversation with a luxury perfume maker. She told us, "My samples look cheap, and it makes customers doubt the real product."
So we built something different. Thick, clear glass that feels substantial in your hand, paired with bamboo caps that screw on tight. We tested them with everything—perfume oils that evaporate easily, vitamin serums that break down in light, even craft spirits that need to stay fresh. Not one leak, not one spoiled sample. They play well with our other products too: pair them with our perfume bottles for scent samples, or match them with Health product bottles to let customers try your supplements before buying full size.
Here’s the thing: these are made in the same factory as our penicillin bottles. That means the same attention to detail, the same quality checks. If they’re good enough for medical supplies, they’re good enough for your brand’s first impression.
What You Need to Know Before Ordering
Materials: We use borosilicate glass (the kind that can handle temperature changes without cracking) and bamboo from FSC-certified forests. The little seal inside? Food-grade silicone, no BPA or weird chemicals that could mess with your products.
Size Details: 22mm across (perfect for standard labels) and 50-60mm tall, depending on how much they hold. We’ve had customers tell us this size fits perfectly in those small gift boxes and makeup bags.
How Much They Hold: 5ml, 10ml, or 15ml. The 5ml is great for perfume samples, 10ml works for skincare serums, and 15ml is perfect for beverage tastings. We can do custom sizes too—just ask.
Where They’re Made: Our factory in China, where we also make 16mm Glass Dropper Bottles and medical containers. Same equipment, same quality team.
Take a Closer Look
These photos show the little details that make a difference—notice how smooth the glass is, how the bamboo cap fits perfectly, and that flat spot where your label will go:
Why These Bottles Stand Out
We didn’t just make another bottle. We talked to 20+ brand owners to find out what they really needed. Here’s what they said mattered most:
The Seal Actually Works: A perfume company tested 50 of these against their old vials. After 2 weeks, 12 of their old vials had leaked; none of ours did. "We’re saving money on wasted product," they said. The silicone ring in the cap doesn’t dry out or crack, so it keeps working.
Customers Notice the Eco Stuff: Bamboo grows fast, and the glass is recyclable. A natural beauty brand said, "We get comments on the packaging in almost every review now." It’s an easy way to show your brand cares about more than just sales.
One Bottle for Multiple Products: A small business owner told us, "I use these for my facial oil, perfume, and body oil samples. I don’t have to order three different containers." They work with thick serums, thin oils, and everything in between—no need for special bottles for each product.
How to Get the Best Results
We’ve learned a few tricks from customers who’ve been using these for years. Here’s what works:
Clean Them Properly First: Wash with warm, soapy water—dish soap works fine. Rinse really well, because any soap residue can mess with scents or formulas. If you’re using them for skincare or supplements, soak in 70% rubbing alcohol for 5 minutes, then let air dry.
Don’t Overfill: Leave a little space at the top—about the width of a penny. If you fill them all the way, product will squirt out when you screw the cap on. We learned that the hard way during testing.
Make Sure the Seal is Right: Check that the silicone ring in the cap is flat (not twisted). Screw the cap on until it’s snug, then give it a tiny extra turn—just enough to feel it seal. Don’t crank it as tight as possible, or you might crack the glass neck.
Apply Labels When Dry: The flat part of the bottle (just below the neck) is perfect for labels. Wait until the glass is completely dry before applying—moisture will make labels peel off later.
Pack Them Carefully: When shipping, wrap each bottle in tissue paper or put them in small foam sleeves. One customer uses those little air-filled plastic pillows around them—says it’s cheaper than replacing broken samples.
How Our Customers Actually Use These
It’s not just about samples. Here are real ways brands are using these bottles:
Perfume Brands: A French perfume house includes a 5ml sample of their new scent with every purchase of their full-size perfume bottles. "It’s like a preview of our next launch," they told us. Customers come back to buy the full size 3x more often than with their old plastic samples.
Skincare Lines: A luxury serum brand sells "travel sets" with 3x10ml bottles—perfect for trips. They say customers are more likely to buy the big bottle after trying the small one, and the sets themselves are 15% of their monthly sales.
Craft Distilleries: A whiskey maker includes 15ml samples with online orders. "It’s a way to let customers try our limited editions," they explained. "We’ve had people buy a $200 bottle because they loved the 50-cent sample."
Gift Sets: A boutique puts together "self-care boxes" with 3-4 of these bottles—each with a different product like bath oil, body serum, and essential oil blend. The bamboo caps make everything look cohesive, and the sets sell for 2x what individual products do.
What This Means for Your Business
It’s not just about pretty packaging. These bottles actually help your bottom line:
Customers Take Your Brand More Seriously: A makeup brand switched from plastic to these bottles and saw their average order value go up by $12. "People perceive our products as higher quality because the samples feel expensive," their CEO said.
You Waste Less Product: A hair oil company was losing $800/month on leaked samples. With these, that’s down to $50. "The seal is so good, we don’t have to replace half our shipments anymore," they told us.
Your Brand Looks Consistent: If you use our health product bottles for your main line, these samples match. No more mix-and-match packaging that confuses customers.
You Simplify Your Orders: A small business owner was ordering 4 different sample containers. Now they use these for everything. "I save 2 hours a week on inventory management," they said. "And my supplier relationships are simpler too."
They Meet the Rules—No Surprises
We know importing can be a headache. These bottles check all the boxes for global markets:
Made in an ISO 9001:2015 certified factory—same as our penicillin bottles, so you know the process is strict.
Passes EU 10/2011 standards—safe for selling in Europe, no matter what’s inside the bottle.
Bamboo caps are FSC certified—proves we’re not cutting down old-growth forests for packaging.
Need copies of any certificates? Just ask our sales team. They’ll send them over in 24 hours—we know you need them fast for customs.
Make Them Your Own
We can tweak these to fit your brand. Here’s what other customers have done:
Branded Bamboo Caps: Laser engrave your logo on the cap. A skincare line did this, and their customers started posting photos of the caps on Instagram. Minimum 5,000 units, but worth it for the free marketing.
Colored Glass: Amber glass for light-sensitive products like vitamin C serums, or frosted glass for a more premium look. One customer matched the glass color to their logo—said it made their gift sets "pop." Works great with our colored 16mm Glass Dropper Bottles too.
Special Seals: Colored silicone rings to match your brand, or extra-strong seals for really fragrant products like patchouli oil. A perfume company used gold seals that matched their logo—small detail, big impact.
Custom Packaging: We can put together gift boxes with your logo, or velvet bags to make unboxing feel special. One brand said their return rate dropped because customers "felt like they were getting a luxury item."
Custom orders take about a month—3 weeks for production, 1 week for testing. We’ll send you a photo of the first sample before making the whole batch, so you can tweak things if needed.
How We Make Sure They’re Perfect
We don’t cut corners. Here’s what happens before your bottles ship:
We Start With Good Glass: We test every batch of glass for clarity and strength. If it has bubbles or imperfections, we send it back. Same standard we use for our health product bottles.
Slow Cool to Avoid Cracks: Glass that cools too fast gets weak spots. We put ours in a special oven that cools them over 8 hours—this is why they’re less likely to break than cheap vials.
Make the Bamboo Caps: We cut bamboo into discs, then machine the threads so they fit the bottles perfectly. Each cap gets a food-safe sealant to resist water—no warping, even if they get wet.
Test the Seal: We fill every bottle with colored water, cap it, and shake it hard. Then we let them sit upside down for 24 hours. If any leak, they get tossed. No exceptions.
Final Check: A person (not a machine) looks at each bottle for scratches, uneven glass, or loose caps. Only the ones that pass get packed up.
What Our Customers Say
"We sell luxury candles, and we started putting our signature scent oil in these bottles as samples. Our repeat purchase rate went up 22%—I truly think the packaging made people take us more seriously. They look amazing next to the perfume bottles we use for our room sprays too."
"As a small-batch gin distillery, we needed samples that didn’t make our product taste like plastic. These bottles are perfect—no weird flavors, and the bamboo caps feel premium. We had a customer tell us they kept the sample bottle as a 'miniature decanter' after using it. The fact that they match the quality of KANG HUA’s other products, like their 16mm Glass Dropper Bottles, gives us confidence in ordering more."
"Our vitamin D drops come in KANG HUA’s health product bottles, so using these for samples was a no-brainer.
How to Order
Payment: We take L/C, D/P, or D/A—whatever works best for your country’s banks. Most customers use L/C for large orders.
When You’ll Get Them: Standard orders ship in 10-14 days. Custom stuff takes 3-4 weeks, but we’ll give you a specific date when you order.
Shipping Options: Ocean is cheapest for big orders (4-6 weeks). Air takes 3-5 days. If you need them fast, DHL or FedEx can get them there in 1-3 days.
Questions We Get All the Time
Q: What if the bamboo cap gets wet? Will it warp?
A: We use waterproof sealing technology, so occasional moisture in the bathroom is acceptable. If the cover is soaked by water, just wipe it dry. However, it should be noted that they must not be soaked in water all the time. They can be used as shower sets.
Q: Can I put thick products like face cream in these?
A: Yep! The opening is wide enough (22mm) that you can get thick creams out easily. A skincare brand uses them for their facial butter samples—they just tell customers to unscrew the cap and scoop a little out with their finger.
Q: Are these recyclable?
A: The glass is 100% recyclable—just put it in your glass recycling. The bamboo cap is biodegradable (you can even compost it). The silicone seal can be reused, but if you’re recycling the glass, just pop it out first. It’s a nice eco-story to share with customers, just like our health product bottles.
