Silicone putty

I was really skeptic about buying this one, but must say it was worth a buy.. It works amazingly for what it is built for.

You get two containers consisting of a blue (silicone) and a white (hardener) substance. Until you mix them it does not dry up. You take equal quantities of both and squish them together till all the blue striation vanish.Then you place it on the object you want to duplicate.You get an ample time to work on it, that is about 8 to 10 minutes if you want the best results.

I made tons of jewellery shapes with this putty.
