Micropuzzles...massive fun! They are 150 pieces and work out to be 4 x 6 finished. Rework them many times or mount them and frame them, or add a magnet, or create! There are so many options! These are such fun little puzzles, and don't let the size fool you! That doesn't mean they are really easy. They challenge you, but yet you can finish them in one day. So much fun!
