This is a folding bag. When folded, it's about 11cm x 17cm (see photo 2). When unfolded, it's 43cm long (see photo 3). When made three-dimensional, it's about 30cm long and 25cm high (depending on what you put in it) (see photo 1). The fabric is thin, so it's best not to put heavy items in it to avoid losing its shape. Perfect for Japanese attire. For those who like it. Thank you for looking.
