10 ml green glass euro dropper bottles are paired here with black tamper evident bulb droppers. Euro dropper bottles are designed with a long neck, including a ring at the end of the threading for pairing with tamper evident caps. Below the ribbed, threaded area of the caps is a tamper evident ring. Once the tamper evident caps have been secured, the tamper evident ring sits just below the collar molded into the neck of the euro dropper bottles. When the tamper evident caps are removed, the perforated ring separates from the caps and remains on the bottle neck, indicating the product has been opened. The glass bulb droppers feature a straight style pipette attached to a polypropylene cap and rubber bulb. The bulb glass droppers can be used to draw the product and dispense it in either drops or a small stream. These small glass bottles could house products like e-liquids, serums, homeopathic remedies, and more!
