Rare junior size. 27.5 cm length and width (amateur measurement) Purchased around 1980, approximately 40 years ago. The box has been repaired with tape, so I've marked it as "has some scratches and stains," but the contents (especially the disc) are in relatively good condition. Please consider the item, keeping in mind that it is a used item stored at home, and carefully review the photos. Please refrain from bidding if you are concerned about the details of the condition. Thank you for your understanding of used items. I have checked the item, but I cannot describe everything, including minor oversights, so please understand. I am not offering price negotiations. Thank you for your understanding.
