Calaso Smooth DIN18mm Threaded Closure

What this packaging is

DIN18mm threading precision meets a clean, slightly glossy finish in this black PP closure — a combination that delivers both a reliable seal and a polished look across a wide range of beauty formats. The Smooth DIN18mm Threaded Closure is designed for bottles with a DIN18 neck finish, making it a natural fit for lip treatments, eye serums, face moisturizers, hair treatments, body scrubs, and body lotions. Sourced from Calaso, a European manufacturer with deep roots in precision packaging components, this closure brings credible quality to brands building primary packaging that needs to perform and present well on shelf.

Why brands choose this

• European manufacturing heritage, built into every thread: Calaso's production roots in the Netherlands signal the kind of component-level precision that matters when a closure needs to seal consistently across high-volume beauty runs — fewer tolerance issues, more reliable compatibility with DIN18 neck finishes.
• One closure, six categories covered: From eye serums to body scrubs and hair treatments, this closure's DIN18 finish spans formats across the full personal care range — useful for brand teams building multi-SKU lines who want a single closure spec to work across the assortment and simplify sourcing.
• Ultra-accessible minimums built for emerging brands: At an MOQ of just 50 units, this closure is genuinely available for small-batch testing, limited-edition drops, or indie brand launches — no large upfront commitment required, which is rare for a precision threaded closure with a professional finish.
