Calaso Smooth 28-410 Straight Sided Flat Threaded Closure

What this packaging is

Aluminum construction gives this closure a premium, weighty feel that plastic simply can't replicate. The Smooth 28-410 Straight Sided Flat Threaded Closure from Calaso pairs a clean flat top and straight-sided profile with a 28/410 neck finish — one of the most versatile thread specs in personal care packaging. It works across a wide range of applications: lip care, eye treatments, face moisturizers, body scrubs, hair treatments, body lotions, and even vitamins or pill packaging. Made to order with minimums as low as 50 units — genuinely accessible for small-batch launches or limited-edition collections — this European-crafted closure brings design credibility and functional reliability to any premium beauty line.

Why brands choose this

• Minimums of 50 units unlock real flexibility: An MOQ of just 50 makes this closure one of the most accessible aluminum options on the market — ideal for emerging brands testing a new SKU, indie beauty founders launching limited editions, or established brands trialing a new format without heavy inventory commitment.
• Aluminum signals premium before the product is even opened: In a category where consumers increasingly associate metal closures with quality and longevity, aluminum construction delivers a tactile weight and surface finish that elevates shelf presence and reinforces brand positioning — particularly relevant as premiumization continues to drive purchasing decisions across skincare and haircare.
• 28/410 neck finish spans an unusually wide range of categories: From lip balm pots to vitamin jars to body scrub containers, the 28/410 thread spec is broadly compatible across personal care and wellness formats — giving product development and ranging teams a single closure solution that works across multiple SKUs and reduces component complexity.
