Thank you for viewing. This is a set of two pairs of beach sandals used by a child. There is no size listed, but the smaller beach sandals are approximately 18.5cm long, and the larger beach sandals are approximately 20.5cm long. Therefore, based on the measurements, the smaller sandals are estimated to be around 16cm-17cm, and the larger sandals are estimated to be around 18cm-19cm. The larger beach sandals have no name written on them, but the smaller beach sandals have marks where a name was erased on the back of both heels. Both pairs have been cleaned. Please understand that these items have been used by a child before purchasing. If you have any questions, please ask in the comments section. Season...Summer
