Cosmetic vials are small containers ideal for serums, oils, and samples, and Guangzhou Hiyeah Packaging manufactures these in glass or plastic with capacities from 2ml to 20ml on our dedicated vial lines. Cosmetic vials from our factory feature precision neck finishes that accept dropper caps, screw caps, or crimp seals, all produced in-house for perfect fit. For cosmetic vials, we offer customization including silkscreen logos, frosted finishes, and custom colors, as well as ecofriendly materials like recycled glass. Our fast sample service (3 days) for cosmetic vials allows brands to test seal integrity and compatibility with their formulas, with bulk orders completed within 30 days. Cosmetic vials are essential for sampling programs, travel sizes, or high-concentration products, and our ISO/FDA certifications ensure safety for global distribution.
