Some puzzles and games can be kept for the whole life, like chess and domino. Not the case of those two polyomino chocolate puzzles. I wouldn't keep a puzzle like that "safe" at home for more than 3 days. The delicious Hanayama puzzles are made with Meiji milk (12 pieces) and dark (11 pieces) chocolate.

The challenge of the puzzle is to put pieces together to form different shapes, after which you'll have to fit everything back into the rectangular box. Sure, and any chocoholic will eat a piece of course! The saddest part is they aren't available on-line, so you have to find a store that sells Japanese products. Ok, I have to go to Liberdade now.
