Giving money or gift cards in a letter or card away is getting somehow really boring over time … that's why we created this puzzle box :-) It's a unique and fun alternative where you have to make your way through the maze in the inside by rotating the case, tilting it carefully, and guiding the hidden nub through the internal labyrinth. It's the last one of this trio and in my opinion the most challenging one 😅 🙈 Have fun with it! P.S. Close the puzzle box according to the little holes placed on the inside, so that the closed box lines up with the outside pattern
