Approximately 34 cm wide x 24 cm high, with a gusset of about 9 cm when expanded. The gusset expands with a zipper, allowing for more storage, and the design becomes sleek when the zipper is closed. It's very user-friendly. The exterior is navy blue genuine leather, and the interior is a cute light purple dotted fabric. The leather part is clean, but the interior fabric shows some stains. They might come off with spot cleaning using detergent. The letter "K" is a cute white stitch. Due to the insole, it cannot be made smaller, so shipping costs will apply. Thank you for your understanding. Please consider purchasing if you understand that this is a used item. ☆ Purchased at Motomachi 3-chome store
