These shoes come with straps, making them difficult to slip off. A set of two sizes: 19cm and 20cm. * The 19cm pair was purchased last year and worn twice, for a piano recital and a wedding. * The 20cm pair was purchased about a month ago and worn once, for a piano recital. Both are from Arisana. They are relatively clean, but please check the images before purchasing. Please refrain from purchasing if you are sensitive to items stored at home. The box is available, but they will be shipped without the box.
