Editorial Review Professional Quality Molds Premium Bullseye molds stand up to repeated use with little maintenance. Ceramic molds from Bullseye are slipcast from a specially formulated clay body, feature exceptionally smooth surfaces, accept kiln wash uniformly, and will not crack under repeated usage when handled properly. Individual molds may have slight variations in dimensions shown. See size perspective of mold with quarter image shown. 3-5/16" x 3-5/16" x 13/16" deep.
