Description
Measure twice with this unputdownable plywood puzzle: open out the two folding rulers and then attempt to criss-cross each around the other to then fit them back into their tray. With steel pivots the snaking, folding shapes will soon have you in a tangle. Inspired by the folding ruler invented in 1851 by German industrialist Johannes Anton Ullrich (1826-95) and from a range of puzzles designed by German-based contemporary puzzle inventor Jean Claude Constantin. An endlessly perplexing challenge to keep brains and hands busy for hours.

Purchased for a sufferer of Alzheimers . They were always used to using their hands and this is sturdy and designed so well it helps to stimulate them. Also suitable for anyone who enjoys a good puzzle😊.
