These are swim caps from Haruoka Swimming School. Levels: 9th, 8th, 7th, 6th, 5th grade. There are 5 caps in total. The 9th, 7th, and 6th grade caps are size M. The 8th and 5th grade caps are size L. They were used consecutively from the summer of the year before elementary school until the summer of 2nd grade, and the sizes were not inconvenient. There are no noticeable scratches or stains, but these are used items, so please understand that they are second-hand goods before purchasing. The tags have names written on them, so I will cover the names before shipping.
