Buy on Amazon

Not everyone likes to purchase putty for their daily purpose, but the instamorph moldable rubber putty would be an anomoly. This product is so much fun to use. It really works for making fake teeth. It is a lightweight polyester thermoplastic which acts like clay when warm, but when it cools, it’s a strong plastic. It can be painted, machined, carved or attached to other materials. It can reuse with hot water. It is great for all ages and skill levels, it can be sculpted with your hands or tools, pressed around an object to make a mold, or pushed into a mold to create a replica.

It definitely has a learning curve to get the right timing down for heating / molding / trimming but the results are really fantastic.

Easy to use and fast drying
Good brand reputation
