This is a set of three baby shoes. The gray shoes are 12cm, and the white shoes and sock-style shoes are 12.5cm. They have been used frequently, but have all been washed and are ready to use upon arrival. To keep shipping costs low, they will be sent via postal mail. To reduce the thickness, the shoes will be lightly compressed for packaging. Please refrain from purchasing if you are concerned about this. These are used items, so please purchase only if you understand that they show signs of wear.
