This is the "Major Kukkiri Zoom" accessory for the Nintendo Game Boy. It is not an official Nintendo product. It is a deadstock item, but the box has some damage due to age. The main unit and instruction manual are deadstock items. The bag is unopened, so we have not confirmed if all the parts are included. This is a very valuable accessory, so would you consider it for collection rather than use? We will ship it promptly via Mercari delivery service, etc. #Nintendo #Nintendo #gb #gameboy #visual #booster #zoom #rare #scarce #retro #rare
