The air brush is very popular in beauty treatments using oxygen. The cup allows you to use your favorite moisturizer, treatment cream or other additive - the oxygen flow then lightly blows the additive onto your face.
Made in the USA of nickel plated brass.
This air brush requires 7 psi or higher to function properly. If you use a high pressure concentrator, you will be able to dispense liquids that are thicker than water. If you're using a low pressure concentrator, you will only be able to dispense liquids the consistency of water and no thicker.
