Tsuburana Hitomi Aquarium. Unopened, unused item. There were 20 types in total, and I worked hard to collect them, but the total number reached close to 50 when I achieved my goal. (^◇^;) I'm listing the duplicate designs for now. Size: Length 7.5 x Width 10.5 x Depth 1.5 (cm) (There may be some errors due to amateur measurements) This is an amusement prize. Although unopened, it is a slightly aged item. I haven't checked it. Please understand that it has been stored by a private individual. Thank you.
