Calaso PP 18-DIN Tamper Evident Ribbed Screw Cap with 0.7mm Vertical Dropper

What this packaging is

A 0.7mm vertical dropper orifice built right into the closure — that's the precision detail that sets this PP 18-DIN Tamper Evident Ribbed Screw Cap apart. Engineered in Europe, this white polypropylene screw cap pairs DIN18 III threading with a natural dropper insert for controlled, waste-free dispensing of serums, face oils, and hair oils. The tamper-evident ring reinforces consumer trust right at first open, while the ribbed collar adds grip and a clean, professional finish that reads well alongside clear or tinted glass. With an MOQ of just 50 units, it's genuinely accessible for emerging brands or small-batch product launches. A smart, functional closure for brands building credibility through precise, elevated application rituals.

Why brands choose this

• Accessible minimums for indie launches and limited runs: An MOQ of just 50 units is rare for a closure with this level of engineering — tamper evidence, controlled dropper dispensing, and DIN18 compatibility in a single component. Emerging brands and indie formulators can test and launch without overcommitting to inventory.
• Dose control that matches how consumers use serums and oils: The 0.7mm vertical dropper orifice delivers a precise, measured drop — critical for high-actives serums and potent hair oils where over-dispensing wastes expensive formulas. As ingredient-conscious consumers pay closer attention to how much they apply, built-in precision is a genuine product experience differentiator.
• DIN18 threading opens up a wide range of bottle compatibility: The standardized DIN18 III thread fits across a broad family of glass bottle formats, which means brand teams can develop multiple SKUs — face serum, hair oil, wellness concentrates — without sourcing a different closure for each. Less vendor complexity, faster development cycles.
