Calaso Smooth 18-400 Straight Sided Tall Threaded Closure

What this packaging is

A glossy, straight-sided tall profile sets this screw cap apart from standard flat closures — giving paired containers a more elevated, intentional look on shelf. The Smooth 18-400 Straight Sided Tall Threaded Closure is made from polypropylene (PP) and fits the widely used 18/400 neck finish, making it compatible across lip care, eye cream, face moisturizer, body scrub, hair treatment, and body lotion formats. Crafted in Europe through Calaso's established closure manufacturing network, it brings design rigor and reliable fit tolerances to every run. With an MOQ of just 35 units, it's genuinely accessible for emerging brands or limited-edition launches looking to prototype or test with minimal upfront commitment.

Why brands choose this

• Ultra-low MOQ opens the door for small brands: At just 35 units, this closure is one of the most accessible ways for indie brands, startups, or limited-edition projects to get a polished, professional cap without committing to large production runs — rare in the closures category.
• Tall straight-sided profile creates visual lift on shelf: Where most 18/400 caps sit low and flat, this closure's taller straight-sided silhouette adds visual stature to the finished package — a small detail that meaningfully changes how a product reads in-store or on a flat lay, especially for skincare and hair care brands investing in premium aesthetics.
• Broad 18/400 compatibility across multiple categories: The 18/400 neck finish is one of the most widely used standards across skincare, hair care, and wellness packaging, meaning this closure can work across lip balm pots, eye cream jars, vitamin bottles, and body lotion tubes — giving multi-SKU brand teams real ranging flexibility without sourcing a different cap for every format.
