Oyumaru reusable modelling compound is unique and amazing. This great Japanese silicone non-stick moulding material is re-usable, so you can keep using and reusing it to make loads of different mold shapes. Perfect if you need to make lots of moulds but only need a few copies cast from each mould. It is a heat-softened and reusable putty that once shaped cools and hardens instantly but stays flexible, plus it does not stick to Art Clay, PMC, polymer clay, Green Stuff/Kneadatite, Stick Putty and other common sculpting putties.
To soften Oyumaru, dip a piece in hot water (approx: 80 degrees C/176F) for about 3-5 minutes. Take the Oyumaru out of the water with a pair of tongs, dry it off with a paper towel and press it against your original to make an instant mould.
Oyumaru picks up fine detail surprisingly well. It is excellent for fingerprints. For gamers and model makers, use it for casting replacements or making your own extra bits like weapons, upgrade parts, pads, armor designs, and anything you need for models and wargaming. You can combine several sticks to make larger moulds.
