Our gear ball is an 8 cm puzzle ball with rotating coloured segments: turn and shift them, scramble them, then work out how to get every face matching again. Each one is 3D printed from PLA to order in Poland and checked by hand before shipping, in three colourways: blue-green-violet, red-yellow-green and gold.
Gifts for a 10 year old boy and for eleven: what gets used every day, what goes on the shelf, small ideas that fit an envelope and what we would leave out.
