Blue Stuff is a thermoplastic putty that is ideal for making molds!
Heat it up in hot water for 3-5 minutes and it becomes malleable. After that you can press any part you want to make a mold of into it. Once cool, use any kind of putty to fill the mold. We recommend Greenstuff or Milliput.
This set contains 8 reusable bars of the material.
