Children's socks, set of 2. With non-slip grips for safety. Used for one season, so there is some pilling and wear and tear. Please purchase only if you understand that these are used items. The size is around 10-13 cm, although I don't remember the exact size. For those who like Shinkansen (bullet trains) or Sanrio, or those looking for spare socks, please consider purchasing. Will be shipped via Yu-Packet Post Mini after waterproofing. Please note that the waterproof packaging may reuse shopping bags, etc.
