Euro Dropper Caps

About

Euro dropper caps give you precise, drop-by-drop control over essential oils, tinctures, serums, and other liquid formulas — without needing to buy a separate insert. Each cap ships with the dropper insert built in, so it snaps onto a DIN 18 Euro bottle and dispenses one drop at a time the moment you invert it.

The tamper evident ring at the base breaks visibly on first use, so your customer knows the seal hasn't been touched before it reached them. HDPE vs. PP: Picking the Right Cap Material HDPE caps are the more affordable, general-purpose option and hold up fine against most essential oils and water-based tinctures. PP (polypropylene) caps cost a little more but resist a wider range of solvents and stronger essential oil blends — citrus oils especially can degrade weaker plastics over time. If you're not sure which one your formula needs, a small sample order is the cheapest way to test compatibility before you commit to a full case. Built for Reliable, Repeatable Sealing These caps thread onto a standard DIN 18 neck finish , so there's no guesswork matching cap to bottle across our Euro bottle sizes. The tamper evident band gives your customers visible proof of an unopened product — something retailers and private label brands increasingly expect as a baseline, not an upgrade. And because the d
