Purchased at Ueno Zoo. I used one each of the B6 and A7 bags, but the others are unused and have been stored. This is a set of 11 UENO ZOO zipper bags, an assortment of 3 sizes. The set includes 3 B5 size bags, 4 B6 size bags, and 4 A7 size bags, featuring cute animals like pandas, anteaters, and ring-tailed lemurs. Since some time has passed since I purchased them, I don't recommend using them for food, but they are perfect for storing small items. Thank you. Although they are in good condition, they have been stored at home, so please refrain from purchasing if you are at all concerned.
