A clean flat top and glossy cylindrical form make this PP closure a natural fit for beauty brands that want simplicity done right. The Smooth 30-Special Straight Sided Flat Threaded Closure from Calaso features a 30mm special neck finish that pairs securely with a wide range of jars and bottles — making it a practical go-to for lip care, eye and face moisturizers, body scrubs, hair treatments, and body lotions.

With European manufacturing behind it, this closure brings consistent quality and design credibility to any personal care line.

Why brands choose this

• MOQ of 1 unit: an almost unheard-of minimum that makes this closure genuinely accessible for indie brands, sampling runs, or small-batch limited editions — you can test fit and compatibility before committing to volume.
• Special neck fit across multiple categories: the 30mm special thread is engineered for compatibility across a broad range of container formats, which means one closure can work across your lip, face, body, and hair SKUs — reducing sourcing complexity for multi-category brand teams.
• PCR material availability for sustainability goals: as clean beauty and responsible sourcing continue to drive purchase decisions, this closure can be sourced with PCR content — giving brands a credible, material-level sustainability story without switching suppliers or redesigning packaging.
