Ergonomically designed to fit in the palm of your hand, Princeton Catalyst Wedges made of flexible, FDA-approved silicone.
 
They're well suited for all heavy body paints — oils, acrylics, and water mixable oils — as well as plaster, clay, and even food crafts. Because they're heat-resistant, they also excel with encaustics.
 
Cleanup is a breeze with Catalyst Wedges  — in most cases, it can be done with mild soap and water. Solvent-resistant, they are simple to wipe clean, and dried paint can easily be peeled off the silicone surface. Catalyst Wedges are also dishwasher safe.
