Calaso 18-DIN Monomaterial Dropper Cap

What this packaging is

Monomaterial PP construction sets this 18-DIN Monomaterial Dropper Cap apart — a single-material build that simplifies end-of-life sorting and keeps supply chains clean. Designed for DIN18 neck finishes, it pairs with compatible glass dropper bottles used for tinctures, face serums, and hair oils. The threaded closure delivers a secure, leak-resistant seal, while the integrated glass pipette enables precise, controlled dispensing. Sourced from Europe, where closure engineering runs deep, this cap brings design credibility to premium liquid formats. With an MOQ of just 50 units, it's genuinely accessible for small-batch tincture brands or product developers validating a new formula before scaling.

Why brands choose this

• Ultra-low MOQ of 50 units: At just 50 units minimum, this cap is one of the most accessible dropper closures on the market — purpose-built for indie tincture brands, apothecary launches, or formulators running controlled test batches before committing to volume.
• Monomaterial PP build simplifies sorting and production: Single-material polypropylene construction means no mixed-material separation at end of life and a more streamlined manufacturing process — an increasingly important consideration as brands face pressure to simplify their packaging material footprint.
• Precision glass pipette meets rising consumer expectations for dose control: Tincture and serum consumers expect accuracy — not guesswork. The integrated glass pipette delivers controlled, repeatable dispensing that aligns with the clinical, wellness-forward positioning driving growth across CBD, adaptogen, and facial oil categories.
