The artist Noah Deledda creates fascinating sculptures. He started with making sculptures from aluminium cans (see https://www.crushmetric.com/pages/about-us). These are individual works of art. He then created the Crushmetric SwitchPen. We have the silver version in the Grand Illusions Shop – see https://www.grand-illusions.com/switchpen-holographic-from-crushmetric-c2x38665824.

Then came the black version of the pen (which we do not sell), the amazing AutoHedron Chair, and now the Crushmetric Tumbler. You can find these on the Crushmetric web site – https://www.crushmetric.com/
