Dropper bottles are small containers designed to hold liquids and feature a dropper cap for precise dispensing. They are commonly used for essential oils, medicines, and other liquid products, allowing users to control the amount of liquid they dispense easily. The dropper typically consists of a rubber bulb and a glass or plastic tube. These bottles come in various sizes and materials, including glass and plastic, making them suitable for different applications. Dropper bottles are often used in the beauty industry for serums and oils, as well as in laboratories for chemical solutions. Their design ensures minimal waste and accurate dosing.
