Set of 3 cast aluminum stamps with wooden handles. Hand wash only. Never submerge wooden handles in water, wipe clean. Chill stamps prior to use. Always use cold dough. If sticking occurs, dip stamp in flour or sugar, or brush with oil. Simply roll dough into balls and press to produce 3D embossed holiday designs with or without frosting. We suggest making cookie dough from scratch when using cookie stamps. Cookie stamp impressions will not be as defined if using prepackaged cookie mixes or refrigerated dough. Made in America of domestic and imported materials
