Smooth 38-Special Straight Sided Flat Threaded Closure

What this packaging is

A glossy white polypropylene closure built to finish the look — the Smooth 38-Special Straight Sided Flat Threaded Closure from Calaso pairs a flat top profile with ridged grip and a 38mm special thread finish for a secure, professional seal. Designed in the Netherlands, where Calaso brings serious design precision to beauty packaging, this PP closure works across lip care, eye products, face moisturizers, body scrubs, hair treatments, and body lotions. Available with PCR content for brands prioritizing material responsibility, and with MOQs starting at just 1 unit — genuinely accessible for emerging brands or limited-edition runs — it's built to integrate with Calaso's container range for a cohesive shelf presence.

Why brands choose this

• Unmatched minimum order flexibility at just 1 unit: An MOQ of 1 makes this closure exceptionally accessible — emerging brands can sample, test, and launch limited editions without overcommitting to inventory, a rare advantage in closure sourcing.
• Multi-category range in a single SKU: Validated for lip, eye, face, body, and hair applications, this closure gives brand development teams a single component that ranges cleanly across a full product lineup — reducing supplier touch points and SKU complexity.
• PCR-compatible for brands with material goals: This closure is available with recycled content included, giving brands a credible, material-specific sustainability story that aligns with growing retailer and consumer expectations around post-consumer responsibility.
