Skrunch!® is 300g of extra fine micro-base silica crystal wrapped up inside a double skinned, highly durable latex material to ensure a supremely comfortable therapeutic massage for the hand and fingers each time you pick it up. It's squidgy, squashy, pulverisable, rollable... you can pull it... drag it... stretch it... dig your fingers into it, firmly, softly, gently, with force or without and we 100% guarantee that, whatever your intention, once you pick up your Skrunch!® you'll find it very hard to put it back down again!
