Thank you for looking! (*^^*) This item was purchased this year at a Mikihouse store and was only used by my child for one season during the summer. The size is 16 cm! I hand-washed it with detergent about once every few weeks, so I think the condition is good, but please understand that it is a used item. After the last use, I soaked it in oxygen bleach and hand-washed it, then dried it thoroughly, so I think you can wear it immediately upon arrival♪ I would be happy if someone would take it. (^^)
