Cosmic Shimmer Glitter Kiss Duos By Creative Expressions. Each Duo is a 50ml jar which contains two colours in one pot to give a variety of unique effects. You can mix them to create an attractive gradient of colour, or use them separately for a contrasting effect. It also has a built-in applicator sponge. It is water-based and fast-drying. You can simply sponge through stencils and masks or directly onto your creation with the included application sponge. The Duos are the newest addition to the popular Glitter Kiss line, which is loved by crafters for it's ability to add a sparkling effect without the need for any adhesive. It can be used on a huge variety of craft surfaces, from card to MDF and other home decor projects.
