Size 23 swimming shoes (insole 14cm)

Selling 2 pairs of used but defect-free water shoes for girls, with non-slip flexible soles, comfortable. Both sizes indicated as C6 or size 23 (one marked C6/23.5, but both are the same), physical insole length 14cm, fits perfectly on the foot and also won't fall off a smaller foot. Suitable for twins. Price indicated for both together, but can separate if buying something else from me. Also selling swimming rings seen in the last picture, new swim diapers (9-15kg), and various swimsuits for girls.
