The manual airbrush gives you full control over the pressure with which your spray is applied. Fine glitter rather than course glitter should be used in order to avoid clogging the pump. Pearl Dust can be mixed with alcohol (grain, vodka, white rum), clear extract (vanilla, lemon, butter), or an essence (rose, vanilla, etc.) to paint with the manual airbrush. The Manual Airbrush by HomeBakers Mart comes with a new lock system and 3 extra reservoirs.
