A cosmetic glass empty bottle set is a collection of empty bottles that are specifically designed for use with cosmetics or other personal care products. The set may include a range of bottle sizes and shapes, such as small, discreet bottles that can be easily carried in a purse or pocket. The set may also include a range of capacities, from small (5 mL or less) to larger sizes (50 mL or more), depending on the intended use and the volume of product required. The capacity of a bottle refers to the amount of product it can hold, and is typically measured in milliliters (mL).
