We have made foam toys with this kit and its fantastic. Does exactly as promised. 2 polymers combining in a chemical reaction to make a squishy toy. Be careful and adhere to the safety instructions.

This product i used specifically to make "fursuit" foam feet with. Following instructions carefully makes great casts. 1 disclaimer, make sure you use it in a warm environment or the solutions become stiff and your cast will fail.

This is a great product. Slightly scary instructions but we found that there were minimal fumes etc. We've made a number of squishies using this. The only trouble is finding suitable moulds to make them from.
