Available here are 5 ml green 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. The caps feature orifice reducers that allow gradual product dispensing when installed into the small green 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 aromatherapy oils, pharmaceuticals, food products, and more!
