This glitter pump bottle holds 30mm/1 ounce of glitter. The bottle is 4.5 tall and 1.25 wide. It is a great tool for applying an even mist of glitter or mica powder on your face painting designs! The nozzle twists down and locks the lid to prevent glitter from escaping when not in use, but we still recommend storing in a plastic bag to avoid accidents. To use, twist the nozzle sideways and upwards and then press down pump slowly for a light mist or press down fully for a heavy mist of glitter.
