Calaso Ribbed 58-400 Straight Sided Flat Threaded Closure

What this packaging is

Ribbed aluminum construction gives the Ribbed 58-400 Straight Sided Flat Threaded Closure its dual advantage: an easy-grip texture that consumers actually appreciate and a sleek silver finish that reads as premium on shelf. The 58/400 neck finish makes it broadly compatible across a wide range of container formats, covering everything from lip balms and eye creams to body scrubs, hair treatments, and vitamins. Manufactured in the Netherlands, this closure brings European production standards to brands that care about consistency and quality. With an MOQ of just 50 units — genuinely rare for a metal closure — it's an accessible entry point for indie brands testing new SKUs or building limited-edition ranges.

Why brands choose this

• 50-unit MOQ unlocks real flexibility: At just 50 units, this closure removes one of the biggest barriers for emerging brands and small-batch launches — no need to over-commit on inventory before you know how a new product or format will perform in market.
• 58/400 neck finish spans a wide category footprint: From lip and eye care to body scrubs, hair treatments, and vitamin jars, the 58/400 thread spec is one of the most widely used in beauty and wellness — meaning this one closure can work across multiple SKUs and reduce your component supplier count.
• Ribbed grip meets premium silver aesthetic: The tactile ribbing isn't just functional — it gives consumers a confident, secure open-and-close experience that's increasingly expected in prestige and masstige skincare. The smooth silver aluminum surface signals quality at first glance, reducing the decoration budget needed to achieve a refined shelf presence.
