Amber glass euro droppers with black tamper evident caps are available here in a compact 15 ml size. Amber glass provides UV protection for light-sensitive components, assisting with keeping your products maintained when storing. Euro dropper bottles feature a long neck, which includes a ring at the end of the threading for pairing with tamper evident caps. The threaded caps are ribbed for an easier grip when opening. Once the caps have been secured into place, the tamper evident ring sits just below the collar molded into the neck of the euro dropper bottles. When the caps are removed, the perforated ring separates from the caps and remains on the bottle neck, indicating the product has been opened. These small glass bottles also feature orifice reducers, allowing for gradual dispensing of products like essential oils, pharmaceuticals, and more!
