Two pairs of children's room shoes. Size: 15-18cm Purchased as a set of two at Costco. The navy blue pair was used by my child and has some wear and tear, with some of the non-slip material coming off (see photo 3). The blue pair is unused. The navy blue pair has been used, so please purchase only if you understand that it is a used item. When shipping, the blue shoes will be separated at the connected part and compressed, and shipped using the cheapest method. Thank you for your understanding.
