This product is handmade. The size is 18cm (height) x 22cm (width), with a gusset of 15cm x 25cm. It can be used as is, but you can also attach a shoulder strap to carry it over your shoulder, or a shorter strap to use it as a handbag. You can customize it to your liking by attaching badges, straps, patches, etc. It's made of T-shirt yarn, so it's a durable construction. Please understand that this is a handmade item. We do not accept custom orders. Please leave a comment if you have any questions.
