Staedtler FIMO Soft Large Block Polymer Clay, White, 454g, 8021-0

Simply heat the soft Fimo in an oven at 110°C for 20 to 30 minutes, and it will harden like ceramic. Unlike ceramics, high temperatures are not required, so you can use your existing oven. Furthermore, because it heats at a low temperature, you can heat additional materials like leather and glass, further expanding the range of your creations. Recommended temperature for use and storage: 15-28°C
