Jo Sonja's Glitter Gels contain tiny light-reflecting particles with the brilliance of rich gold or opal. Use alone or with acrylic colours to create glitter effects on most surfaces. Suitable for use on surfaces such as paper, card, glass, plastic, canvas, wood, teracotta, tin and fabric, Jo Sonja's Glitter Gels are non-yellowing and the brushstrokes disappear when dry.
