Made from PLA+ for extra strength. Our cookie-cutter designs have a depth of 13 mm and indentions of 10 mm in height, with a reinforced base to give them extra strength. Dough with a height of 5 mm works best with these cookie cutters. For the easy release of dough, remember to coat the cutter with icing sugar/ flour before cutting. We also recommend using chilled dough for best results. We generally use blue PLA+ to make the cookie cutter, but please be aware the color may vary. This product is not dishwasher safe, hand wash in warm or cold water.
