Oyumaru - Molding putty

Oyumaru is a japanese reusable putty, which gets soft when put in hot water 80°C for a few minutes. Press the putty on the object one wants to copy as long as it is soft and let it cool of (takes just minutes) It can now be used to shape precious clay in the putty mold.
It can be reshaped by putting it in hot water again, over and over again.
The Oyumaru stick comes in different colors and is 5,7 x 1,5 x 0,7 cm.
