craighill | puzzles | spheres | stainless steel
Desktop accessory maker Craighill’s stainless steel puzzle forms a complete sphere when assembled, but figuring out how to put its three components together is harder than it looks. It measures the same diameter as a pool ball, but weighs a hefty 1 lb, 12 oz. Pre-order price available for a limited time from Drop.
