Melissa & Doug Wooden Puzzle Sound This is a Melissa & Doug wooden shape-sorting puzzle. It makes sounds, so I think children can enjoy it from a young age♪ Overall, it seems to be in good condition, but there are some areas with minor scratches as shown in photo 4. It's a battery-operated type. The sound still works, so you should be able to play with it for a while without changing the batteries. It uses 2 AAA batteries. From the popular American brand Melissa & Doug, loved for many years, this is a sound puzzle. The "Sound Puzzle Musical Instruments" is a sound puzzle where the sound of the instrument plays when you put the instrument piece in place. Unlike regular puzzles, it makes "sounds," so it's a shape-sorting puzzle that you can enjoy with your ears in addition to the fun of putting the puzzle together. By putting the puzzle pieces in place, it improves fine motor skills, and by finding the pieces that match the shapes, it helps develop spatial awareness. It has pegs, so even young children can easily remove the pieces! #Melissa&Doug #WoodenPuzzle #SoundToy #Puzzle
