Blue Stuff is the fastest way to clone a part you love. Drop the bars in hot water for three minutes, press the softened plastic against your original, and in moments you've got a reusable mould ready to cast copies in putty or resin. This is the bigger 8-bar pack — handy when you're moulding larger pieces or several at once.
Why it's good
Enough material for larger moulds or batch casting
Works with putty, polyester and epoxy resins
The pack to grab when one bar was never going to be enough.
Reusable instant moulds, double the material. Pair with a tin of modelling putty for casting.
