This is a foldable mini eco-bag. Open: 31.5 x 28 cm Folded: 9 x 13 cm No inner lining. It's the perfect size for a quick shopping trip. My child uses it as a shoe bag. I tried putting in a new pair of shoes. 24 cm shoes fit (see photo 5). 26.5 cm shoes were a tight fit, but they went in (see photo 6). An A4 envelope sticks out a little at the top. It folds up compactly, making it convenient. This is handmade by an amateur, so it's not perfect. I would be happy if you still like it. 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 this with other items, please comment. I will give you a small discount. #KurokaHandmadeWorksList #MiniEcoBag #ShoeBag Material: Cotton
