Calaso 0.5oz /15ml 18-400 Glass Square Bottle

What this packaging is

Inspired by the Myrtle plant, this flint glass square bottle has an inner wall that thickens toward the base — creating a weighted, sculptural presence that flat-sided bottles simply can't match. The 0.5oz / 15ml Glass Square Bottle with an 18-400 neck finish works across eye cream, face serum, face moisturizer, tincture, and sampling applications, and accepts a wide range of closures. Decoration options include silk screen printing, heat stamping, etching, frosted finish, and spray coating. European manufacturing brings serious design heritage to a format that gives indie and established skincare brands alike a genuine shelf identity.

Why brands choose this

• Ownable silhouette that earns a second look: The Myrtle-inspired square form with a thickening inner wall creates a weighted, architectural base that reads premium on shelf and in flat-lay photography — giving brands a distinctive visual identity without custom tooling.
• Decoration depth that supports real brand expression: Compatible with silk screen printing, heat stamping, etching, frosted finish, and spray coating, this bottle gives product developers serious customization range — whether the brief calls for a clean apothecary look or a fully branded luxury aesthetic.
• Accessible minimums for emerging brands or limited-edition runs: With an MOQ of 108 units, this made-to-order bottle is genuinely accessible for small-batch launches, sampling programs, or new SKU testing — removing the financial barrier that usually comes with glass packaging at this quality level.
