The objective is to not just free the 20 euro-cent coin but to actually open the puzzle box.

Availability In stock


Jean-Claude’s original version of the 20 Cent Box had a goal to remove the 20 cent coin.  In 2020 he redesigned the box to incorporate a key that will now open the puzzle box completely. But where to find the key?
To open this puzzle box you’ll really have to think outside the box; outside the PUZZLE box that is!

This version is an original made in the workshop of Jean Claude Constantin himself and does not come with commercial packaging. Jean-Claude is a German puzzle inventor and maker well known for his very high quality and creative puzzles sold at local markets throughout Germany and to collectors around the world.  He does not export very many puzzles and we are very pleased to be able to offer a small selection of his puzzles including this e-box. We have very few of the puzzles available.

Made of laser-cut wood with stainless steel parts.
Size: 75mm x 52mm x 40mm
