Used only once for a nursery school entrance ceremony, and now being sold because my child has outgrown them. They are relatively clean, so they are practically unused. In the photos, they appear to be a grayish color on black velvet fabric, but this is due to the light reflecting off the velvet surface and is not a stain. The size is indicated on the box in EU size 23, which is 14.4 cm in Japanese size (centimeters) (see photo 4). I purchased them for 5000 yen. The product site lists them at 27.90 euros (approximately 4400 yen in Japanese currency). Made of natural cotton with a natural rubber sole. These are formal baby shoes from the Spanish brand Cienta. The following is the Spanish product site: https://www.cientashoes.com/es/bailarina-salon-terciopelo.html#92=58 Here is a Japanese translation of the site information: Cienta specializes in the manufacture of children's shoes, using only natural materials to provide lightweight shoes suitable for the needs of young children. The velvet ballerina is an original design model that can be paired with any look. This model is made of organic cotton, and the sole is vulcanized rubber. The inside of these Cienta girls' ballerinas is lined with synthetic mink fur and has a Velcro closure for added support. Style and comfort in one model!
