Thank you for viewing! I believe this was a souvenir from the Okinawa Churaumi Aquarium a long time ago. I think it's a product that's hard to find now. A Heisei-era retro notebook. Size (approx.) 18cm tall x 12.5cm wide *Please note that there may be some errors due to amateur measurements. Since it's old, there may be some scratches and stains. Please check the photos for stains, etc. Please understand that this is stored by an amateur and kept at home, and purchase with your understanding. A retro, cute, and rare notebook that is hard to get now. How about adding it to your collection? #DuffyMayShop If you are buying multiple items, please leave a comment and I will give you a discount. Anonymous shipping.
