You can study English, kanji, and math in a game-like format. It comes with earphones, so you can study anywhere. Includes custom stickers. The main unit and earphones have been wiped with alcohol, but there are some stains (discoloration?) that won't come off. They don't show up well in the photos. Due to shipping thickness, the box will be folded and included. Please understand. Only those who understand that this is a used item, please. #Challenge
