Amber 30 ml glass euro droppers with black polypropylene straight glass pipette droppers can make an excellent choice for packaging products like aromatherapy oils, pharmaceuticals, food products, and much more! Amber glass provides UV protection for light-sensitive components, assisting with keeping your products maintained when storing. The bulb glass droppers include tamper evident rings. The tamper evident ring will detach from the rest of the cap when the essential oil bottle is first opened for added security.
