Product Description
Oyumaru or Instant Mold is a fabulous reusable instant moulding material!
This great Japanese silicone non-stick moulding material is re-usable, so you can keep using and reusing it to make loads different mould shapes. Perfect if you need to make lots of moulds but only need a few copies cast from each mould.
Oyumaru is a reusable putty, which is softened by heat (put it in a mug of hot water). Once shaped it cools and hardens in just minutes into a hard, slightly rubbery, plastic. It does not stick to Art Clay, PMC, polymer clay, Green Stuff, Kneadatite, Epoxy Putty, Stick Putty and other common sculpting putties.
This product is sometimes referred to as Instant Mold.
Oyumaru/Instant Mold picks up detail surprisingly well. It is excellent for fingerprints (and for our gamers and model makers; casting replacements or making your own extra bits like: weapons/shoulder pads/armour designs/boneswords/lash whips/fairy wings for army models/nids/wargaming/faery making).
- Place the Oyumaru block in hot water for a few minutes (a mug with hot water from the kettle works great)
- Once soft, shape as you like or impress original. If you change your mind and want a new mould, just re-heat in water and start again! And again. And again. And... so on.
- Once happy, leave your mould to cool off and harden, and then it will be ready to use!
Combine several sticks to make larger moulds.
PS. Don't put this on your hotplate to dry your metal clay - your mould will soften and lose its shape! Only air-dry until the metal clay is dry enough to pop out of the mould.
No shelf life. Can be heated and moulded over and over.
Each stick is around 6cm long, and you get a box of 7.

Excellent
Brilliant product - easy to use, does go hard quite quickly but easy to soften after placing back in hot water. Managed to get fingerprint mould.

Fantastic and easy to use
This is great stuff, and you can make models which are detailed and accurate. It's also a bargain, because you can reuse it many times.

Brilliant product, very easy to use and reuse.

Fantastic product
This is an extremely easy to use product which, being remouldable, is great if you're either new to moulding & casting or if you want to only make a couple of copies of something. Detail retention is exceptionally good, and I've not encountered problems of parts warpage due to the heat even when moulding from resin. Parts can be made in putty (like GS) or resin with equal ease - definately highly recommended.

Geat product
Used this product to cast fine detailed models and works really well. Just needs a bit of practice to get used to.

Quick & easy!
Really easy to use and gives very good detail. Really hot water from an almost boiling kettle works best. If the mould isn't what you want just put it back into the water and remould. Really good value.
