Thank you for viewing. Hanamaya Meiji Milk Chocolate Puzzle Difficulty: Pure (Sweet) A puzzle that looks just like Meiji Milk Chocolate. It's a puzzle where you fit 12 pieces, each made of 5 squares, perfectly into the case. Each piece is a collection of 5 squares. These shapes are called pentominoes. There are 2339 possible solutions to fit them perfectly. Furthermore, you can enjoy playing with the 12 chocolate pieces to imagine various shapes. The packaging is damaged. For the listing, I have wiped it with alcohol.
