Smooth 39-Special Straight Sided Flat Threaded Closure

What this packaging is

A 39mm special neck finish sets this closure apart — it's a precise fit detail that matters when you're building a cohesive multi-SKU line. The Smooth 39-Special Straight Sided Flat Threaded Closure from Calaso is a PP closure with a flat top and clean straight-sided profile, designed to complement everything from lip balms and eye treatments to body scrubs and hair care. Sourced from Europe, Calaso brings real design sensibility to a component category that often gets overlooked. With an MOQ of just 50 units, it's genuinely accessible for emerging brands testing formulations or launching limited editions. A minimalist finish that lets your label do the talking.

Why brands choose this

• MOQ of 50 units removes the usual barrier: At just 50 units minimum, this closure is one of the most accessible entry points in the category — purpose-built for indie brands, R&D sampling, or limited-edition drops where committing to thousands of units simply isn't practical.
• Multi-category range from a single SKU: Compatible end uses span lip, eye, face, body, and hair — meaning brand teams can standardize on one closure across an entire product family, cutting down supplier complexity and creating visual cohesion on shelf.
• Flat-top profile suits the clean beauty aesthetic driving purchasing decisions: The straight-sided, flat-top form reads as intentional and modern, aligning with the minimalist packaging trend that continues to dominate prestige and clean beauty retail — no extra decoration needed to look considered.
