This is an educational toy set with colorful parts and an electric drill. Children can assemble the parts into various shapes and play with them. It's perfect for nurturing children's creativity and concentration. The case can be opened and used as a stage for play, and everything can be stored inside when finished. Some parts are missing. Used a few times, but there are no noticeable scratches or stains. The cover of the instruction manual is detached, but you can actually build freely without it. The electric screwdriver has been tested and is working. Thank you.
