Twinkling H2O's are little pots of concentrated mica paints. The mica adds a brilliant shine to your projects. They come to you in "hard" cake format in either a 5gm or 10gm little jar. Simply spritz with water to activate. Use a paintbrush or waterbrush to pick up the color. When you're done using them, let dry and store. These jars go a long long way! Collect them all!
