The Christmas Mug Rim Cookie Cutter Set includes three cookie cutters in the shape of a tree, a star, and a gingerbread boy, ranging in size from 2 inches to 2.5 inches. Each one has a notched base to create cookies that will sit on the rim of a mug. These cookie cutters are made from tin-plated steel to prevent rust. Deep sides create sharp defined cuts so cookies hold their shape while baking. Use these cookie cutters for roll-out cookie dough, fondant, and crafts. Hand wash and dry thoroughly.
