This 5-chamber split silicone cup is used for creating geodes (so-called geode art), decorated pictures, coasters and other decorations, mainly from crystal resin. Each chamber can be filled with a different colour of resin, and these colours can then be poured simultaneously side by side, creating original effects. The cup is reusable – once the resin has cured, any residue can easily be peeled off the silicone surface. The cup can also be used for creating with acrylic paints, so-called fluid art.
