Chameleon Alcohol “inks”, Fill each bottle to the shoulder (approximatly 20ml) of 91% Isopropyl Alcohol. You can use 70% in a pinch, but is may not function as well depending on your epoxy. Shake well before each use. Make sure when replacing the nozzle to push in until you feel the “click”. If your bottle is leaking then it isnt in all the way. Elementals function best on Black bases but can be used on white for a totally different look.
