While most puzzles may be 2D, the 'Piggy Bank Puzzle' is one that comes complete with three full dimensions once finished. The kit comes in 48 pieces that you use to build your very own piggy bank.
There are different designs for the Piggy Bank Puzzle: Mickey and Minnie Mouse, Hello Kitty and Neon Genesis Evangelion.
Implications - Children may be hard to please at times, but a little thought going into product design for kids may take them a long way. The featured piggy bank doubles as a toy which makes the item more valuable to a child. Not only can they store money in it, but they can also build a puzzle, which helps to build up their fine motor skills.
