Open: 31.5 x 28 cm Folded: 9 x 13 cm No lining. Perfect size for a quick shopping trip. My child uses it as a shoe bag. I tried putting in new shoes. 24 cm (photo 5) 26.5 cm shoes fit, but it was a bit tight. (photo 6) An A4 envelope sticks out a little. It folds up compactly, so it's convenient. This is handmade, so it's not perfect. I'd be happy if you like it anyway. It will be sent folded, so there will be fold marks. #Recommended for those who are not good at handmade items, entrance and school preparation set If you purchase together, please comment. I will give you a discount, but it's a small one. #Kuroka Handmade Works List
