Calaso Smooth 58-400 Straight Sided Flat Threaded Closure

What this packaging is

A 58-400 neck finish is one of the most widely used thread specs in beauty and wellness, and this PP closure is built to match it cleanly across lip care, eye care, face moisturizers, body scrubs, hair treatments, body lotions, vitamins, and pills. The Smooth 58-400 Straight Sided Flat Threaded Closure from Calaso features a ridged outer edge for easy grip and a flat top that takes decoration well — made to order through Impacked Packaging with minimums as low as 50 units, making it genuinely accessible for indie brands, test launches, or tight limited-edition runs. A clean, glossy white closure that works across categories without looking generic.

Why brands choose this

• Remarkably low MOQ for a functional closure: At a minimum order of just 50 units, this closure is one of the most accessible options on the market for emerging brands, limited-edition launches, or early-stage product development — letting you test across SKUs without overcommitting inventory.
• One closure, eight end-use categories: Compatible with lip, eye, face, body, hair, and wellness formats including vitamins and pills, this 58-400 threaded closure reduces component complexity for brand teams ranging across product lines — fewer vendor relationships, more consistent packaging architecture.
• Flat top geometry invites brand expression: The smooth, flat lid surface is well-suited for label application, hot stamping, or pad printing, giving brands a clean canvas to work with on a format that would otherwise read as purely functional — a small detail that matters at shelf.
