Boba-straw construction cube hubs

Build large frames from drinking straws

Closed 32 mm cubes with a 12.5 mm socket on all six faces: push in 12 mm bubble-tea straws, cut to any length, and build frames, towers and domes that are light, cheap and big enough to sit inside. Straws snip with scissors, so children design their own lengths.
