Calaso Smooth 58-400 Straight Sided Flat Threaded Closure

What this packaging is

A glossy, flat-top PP closure with a clean straight-sided profile, the Smooth 58-400 Straight Sided Flat Threaded Closure from Calaso is built for the 58/400 neck finish — one of the most widely used standards across cosmetic and wellness packaging. In classic black, it pairs naturally with glass or plastic jars used for face moisturizers, eye creams, lip balms, body scrubs, hair treatments, body lotions, and even vitamins or supplement containers. Manufactured in the Netherlands, it brings European production standards to brands that care about consistency and finish quality. With an MOQ of just 50 units, it's genuinely accessible for small-batch launches or limited-edition packaging projects.

Why brands choose this

• Accessible at just 50 units per order: An MOQ of 50 makes this a practical option for indie brands, formulators, and studios testing new SKUs — no need to over-commit on inventory before you know what's moving.
• Wide category compatibility drives range efficiency: Fits naturally across lip, eye, face, body, hair, and supplement categories — making it a single closure solution for brand teams building multi-SKU lines without juggling multiple components.
• European manufacturing brings consistent precision: Produced in Hoogeveen, Netherlands, this closure reflects the tighter dimensional tolerances and finish consistency that European manufacturing is known for — reducing the risk of seal failures or cosmetic defects across production runs.
