Calaso 18-DIN Bulb Dropper

What this packaging is

Child-resistant and precision-engineered, the 18-DIN Bulb Dropper is a PP pipette closure built for accurate, drop-by-drop dispensing of face serums and hair oils. The DIN18 thread ensures broad bottle compatibility, while the matte ribbed collar adds grip and a clean, professional finish. Developed by Calaso with European manufacturing heritage behind it, this dropper reflects the kind of closure expertise that shows up in the details — consistent bulb tension, a straight tip for controlled application, and a sleek black colorway ready to pair with premium glass or plastic bottles. MOQ starts at just 35 units, making it genuinely accessible for small-batch and emerging brands.

Why brands choose this

• Remarkably low 35-unit minimums: At an MOQ of just 35 units, this dropper is one of the most accessible closure options available — ideal for indie brands testing new formulas, limited-edition drops, or small-batch serums where overcommitting on components isn't an option.
• Precision application that matches consumer ritual: The bulb-and-straight-tip design gives consumers tactile control over every drop — a format that aligns directly with how people expect to apply serums and scalp treatments. Dose control reduces waste and builds trust in the product experience.
• Child-resistant closure with broad bottle compatibility: The DIN18 thread fits a wide range of standard bottle necks, so brands aren't locked into a single bottle supplier. The built-in child-resistant mechanism adds a safety credential that's increasingly expected for liquid actives and oil-based formulas sold across multiple retail channels.
