Available here are 50 ml amber glass euro dropper bottles with black tamper evident caps. Euro dropper bottles have a longer neck, including a ring at the end of the threading for pairing with tamper evident caps. Amber glass provides UV protection for light-sensitive components, assisting with keeping your products maintained when storing. The caps feature orifice reducers that allow gradual product dispensing when installed into the 50 ml amber bottles. Once the cap is screwed entirely on the glass bottle, the orifice reducer will remain snug in the opening, ready for use. The tamper evident ring will detach from the rest of the cap when the bottle is first opened for added security. Euro dropper bottles make a top choice for packaging products like essential oils, pharmaceuticals, food products, and more!
