Description

Oyumaru is a Japanese reusable thermoplastic molding compound used to create detailed molds for metal clay, polymer clay, resin and other craft projects. The material softens in hot water (approx. 80 °C / 176 °F) after a few minutes. While warm and flexible, press it onto the surface you want to copy. It hardens as it cools and becomes a ready-to-use mold.

The material can be reshaped unlimited times by reheating it in hot water. Multiple sticks can be combined to create larger molds. Available in various colors. Size per stick: 5.7 × 1.5 × 0.7 cm.
