I purchased this at Nishimatsuya, but my child finished using diapers before I could use it. There's no size label, but my 4-year-old son currently wears 100cm bottoms, and this seems to have room, so I think it's around 110cm. I'm not sure if it will be used for a short period, but I'm listing it because it might be needed when going out. I'd like to offer it to someone who could use it. Although it hasn't been used, it has been stored in the closet for a long time, so please refrain from purchasing if you are a meticulous person. Also, please be aware that there is no clear size indication when purchasing.
