A new version of an old box. This is the second style of the 20 Cent Box. Unlike its predecessor (whose objective was to free the coin), the objective is to open the box. Insert the coin into the opening on the top of the box. There is a hidden metal key that will help to solve the puzzle.
Made in laser-cut wood and stainless steel by Jean-Claude Constantin. Jean-Claude Constantin lives in Germany, where he designs and manufactures many different wood and metal puzzle, as well as magic tricks.
