Calaso 1.0oz /30ml 18-400 Glass Round Bottle

What this packaging is

Anti-rotation nocks and a slender cylindrical silhouette make the 1.0oz / 30ml 18-400 Glass Round Bottle from Calaso's Willow collection a standout pick for dropper-format applications. Crafted in Europe by a manufacturer with deep glass heritage, this clear flint glass bottle pairs precision with an elevated, minimalist aesthetic. The 18-400 neck finish accommodates dropper assemblies seamlessly — a natural fit for face serums, eye treatments, tinctures, and fragrances. Decoration options span silk screen, heat stamping, etching, frosting, and spray coating, giving brand teams serious customization range. With accessible minimums for emerging brands or limited-edition runs, this bottle suits launches at almost any scale.

Why brands choose this

• Dropper-ready design supports high-ritual categories: The 18-400 neck and slender Willow silhouette are purpose-built for droppers — the format that's become synonymous with face serums and tinctures. As consumer demand for precise, clinical application continues to grow across skincare and wellness, this bottle delivers the form factor that signals efficacy before the cap is even removed.
• Six decoration methods, one component: Silk screen, heat stamp, etching, frosting, tampo pad, and spray coating are all compatible — meaning brand teams can develop distinctly different SKUs or seasonal editions off a single bottle without switching suppliers or tooling.
• Accessible minimums at 108 units open the door for small-batch and limited-edition launches: At just 108 units MOQ, this is one of the lowest-commitment glass bottle options available — genuinely rare at this format quality. Perfect for indie brands testing a new serum, wellness brands sampling a tincture line, or established brands doing a capsule fragrance run.
