Calaso PP 18-DIN Tamper Evident Ribbed Screw Cap with 1.6mm Vertical Dropper

What this packaging is

A 1.6mm vertical dropper orifice strikes the right balance — enough flow for smooth application, controlled enough to prevent waste — making this PP 18-DIN Tamper Evident Ribbed Screw Cap a precision tool for tincture brands that take dosing seriously. The matte black polypropylene closure pairs a ribbed collar for grip with a clean bulb-head silhouette that reads premium against clear or colored glass. An integrated tamper-evident ring protects product integrity from the moment it leaves your facility. European-manufactured to tight tolerances, with DIN18 III thread compatibility for a reliable seal. At just 50 units minimum, it's genuinely accessible for small-batch tincture launches or limited-edition runs.

Why brands choose this

• Ultra-low MOQ unlocks small-batch and specialty runs: At a 50-unit minimum, this closure is one of the most accessible tamper-evident dropper caps available — purpose-built for emerging tincture brands, formulators testing new SKUs, or limited-edition drops that can't justify high upfront commitments.
• Tamper-evident design meets tincture category compliance expectations: The integrated tamper-evident ring isn't just a safety feature — it's a consumer trust signal that's increasingly expected in the tincture and liquid actives space, where product integrity and regulatory optics matter at both retail and DTC.
• Precision 1.6mm orifice supports dose-controlled consumer rituals: Tincture consumers are measuring, not pouring — the 1.6mm vertical dropper delivers consistent drop-by-drop control that reduces waste, builds user confidence, and reinforces the clinical credibility that wellness and functional supplement brands work hard to establish.
