This is a cute drawstring bag that becomes a frilly mouth when cinched. The large size is recommended for a change of clothes bag, and the small size is recommended for a lunch bag. Also, it comes with a hook string, so you don't have to worry about the string touching the floor when hung. You can also iron on patches if you like. Patches are 1400 yen per bag. Please let me know which one you would like in the comments. I will change it to a dedicated listing. Sizes: Large: Approximately 30 x 26 cm Small: Approximately 26 x 20 cm There may be some distortions unique to handmade items. Please understand this before purchasing.
