Aladine is a French company and they manufacture some pretty cool products. This izink Pigment ink is one of them. You can use it with paper, wood, metal or plastic. It is permanent and can be diluted with water or alcohol when you add it to a spray bottle.
You can paint with it, drip it down your journal or canvas, etc. The glass bottles are 15ml and come with a glass eyedropper. They have lovely saturated colors. I can’t wait to start experimenting with them!
