I'm not very familiar with this, but after checking information from other sellers, it seems these are platform boots that were released on October 31, 2022, for Kuromi's birthday (one of a set of two). This is a must-have item for Sanrio character collectors, especially those who love Hello Kitty and Kuromi! Features include black boots with ribbons and Kuromi character embroidery. The size is listed as S, so I believe it's around 22cm to 23cm (the outsole length is 23cm). *Please note that the product information is based on information from other sellers. - Color: Black - Design: Lace-up with ribbons - Embellishment: Character embroidery - Heel Height: Approximately 7.5cm Thank you for looking.
