Calaso Smooth 40-400 Straight Sided Flat Threaded Closure

What this packaging is

An MOQ of just 50 units makes this closure one of the most accessible entry points in professional-grade cap sourcing. The Smooth 40-400 Straight Sided Flat Threaded Closure is a polypropylene cap with a 40/400 neck finish, designed to pair with a wide range of containers across skincare, haircare, body care, and wellness categories — from facial moisturizers and eye creams to body scrubs, hair treatments, lotions, and vitamin or supplement bottles. Its clean flat profile and smooth matte white finish offer a neutral, modern base that works across brand aesthetics without competing with your label or decoration. Made to order through Calaso's European manufacturing network, this cap is built for brands that want reliable, precise threading and a consistent seal without locking into high-volume commitments.

Why brands choose this

• Genuinely low minimums for real brand flexibility: At just 50 units MOQ, this closure is one of the few professionally manufactured PP caps accessible to indie brands, limited-edition launches, or product developers testing new formulas before scaling — dramatically reducing upfront inventory risk.
• One neck finish, a dozen product categories: The 40/400 thread standard is broadly compatible with jars and bottles used across lip, eye, face, body, hair, and wellness supplement formats, making this a single cap SKU that can simplify vendor management across a diverse product range.
• Clean, flat form that stays out of the way: The smooth matte white profile gives formulators and brand teams a neutral canvas — it doesn't fight with custom labels, sleeves, or hot stamp decoration, and its straight-sided geometry photographs well for DTC and retail product imagery.
