The set of diamond-shaped plunger cutters consists of 4 different sizes, suitable for making diamonds from gum paste, fondant, modeling clay, marzipan. Ideal for decorating cakes, pies, and muffins. With the help of a plunger cutter, you can easily and effectively create beautiful decorations. To use the diamond-shaped cutters correctly: 1) Roll out your sugar paste (fondant, marzipan, gum paste, modeling clay) thinly. We recommend using a silicone mat as a base (sold separately). You can sprinkle with icing sugar or cornstarch. 2) Press the cutter into the material without pressing the plunger. 3) Press the plunger down to create the shape. 4) Lift the cutter. Now you can press the plunger to eject the diamond. Size: 2.6 x 1.7cm, 1.4 x 1cm, 1.1 x 0.7cm, 0.9 x 0.6cm
