Calaso Smooth 28-410 Straight Sided Flat Threaded Closure

What this packaging is

A flat, smooth aluminum cap that disappears into your packaging design — in the best way. The Smooth 28-410 Straight Sided Flat Threaded Closure from Calaso pairs precision threading with a clean, unmarked top surface that's ready for hot stamping, labels, or any custom decoration your brand needs. The 28/410 neck finish gives it broad container compatibility across lip care, eye care, face moisturizers, body scrubs, hair treatments, and body lotions. Made to order with an MOQ of just 50 units — genuinely rare for aluminum closures — making it an easy call for emerging brands, indie launches, or limited-edition runs.

Why brands choose this

• Accessible minimums that almost never exist in metal: With an MOQ of just 50 units, this aluminum closure removes the usual barrier to entry for metal packaging. Emerging brands, limited-edition drops, and sampling programs can all access a premium aluminum finish without committing to large production runs upfront.
• Blank canvas top surface built for brand expression: The smooth, unmarked flat top is purpose-built for customization — labels, hot stamping, screen printing, or embossing all work cleanly on this surface. In a market where closure real estate is increasingly treated as brand touchpoint, that flat top is valuable space.
• Wide category reach simplifies sourcing across your range: The 28/410 neck finish is one of the most widely used standards in beauty and wellness packaging, making this closure compatible with containers across lip, eye, face, body, hair, and supplement categories. Brand teams ranging multiple SKUs can standardize on one closure and reduce supplier complexity.
