1oz/30ml 18-400 Clear Glass Cylinder Cosmetic Bottle for Serums, Perfume, & Foundation

What this packaging is

Clear glass and a precise dropper format make this 30ml cylinder bottle a natural fit for face serums, face oils, and CBD oil — categories where consumers expect both clinical precision and shelf credibility. The 1oz/30ml 18-400 Clear Glass Cylinder Cosmetic Bottle features an 18-400 neck finish that's broadly compatible with droppers, pumps, and other dispensing closures, giving brands flexibility at the fill stage. Its slim cylindrical silhouette (3.12" H × 1.3" D) works well on crowded retail shelves and leaves clean surface area for silk screen or transfer printing. Manufactured in South Korea, a region with strong cosmetic glass heritage, this bottle brings quality and reliability to premium skincare and wellness lines.

Why brands choose this

• 18-400 neck finish keeps closure options open: The standard 18-400 finish is compatible with a wide range of droppers, treatment pumps, and orifice reducers — so brands can test different dispensing formats against the same base bottle without sourcing a new component, which keeps development timelines lean.
• Clear glass turns product color into a selling signal: Transparent glass lets the formula speak — amber serums, golden face oils, and tinted CBD blends all become visible purchase cues on shelf. This is especially relevant as consumers increasingly scan ingredient quality visually before they even read a label.
• South Korean glass manufacturing brings cosmetic-grade consistency: South Korea has a well-established cosmetic packaging manufacturing base with high quality-control standards. For brands building premium skincare or wellness lines, that consistency in wall thickness and clarity matters at the filling stage and on shelf.
