EZ Dotz are used to make different sized dots by dipping the different sized ends into paint and applying it to your surface. This tool set makes creating intricate mandala designs a breeze! This is my favorite tool in the studio because I love polka dots and mandala designs. This tool can be used with ceramic paints or acrylics. Be sure to wash it off right after using with acrylics because they dry hard on the surface where as ceramic paints wash away more easily.
