This is a great way to get fine lines and precise control of fluids all in one simple set. For use with any non corrosive paste, liquid or gel. The one ounce bottle is ideal for storing your liquid. The 1/2 oz bottles holds approx half the amount. Includes two 1/2 oz & two 1 oz soft squeeze bottles, 4 plastic syringe caps (to hold the tips), 5 Machined Stainless Steel half inch blunt tips (gauges 20, 19, 18, 16, & 14 -smallest size to largest size). These are NOT used to pierce the skin. They are used for applying henna on TOP of the skin. Cleaning pins (used for clearing clogs and cleaning tips). Be sure to keep the applicator full. As the bottle empties it gets harder to squeeze.
