Size...17cm or more Thank you very much for viewing my product from among many others. These are Crocs rain boots that my child used. I'm selling them because they're too small now. They show signs of use, but... I think they're still usable. There are no noticeable stains or tears at a glance, but... I'm an apparel novice, so I apologize if I missed anything.... There is a name written on the inside of the rain boots, so I plan to cover it with a marker. *If you use Eco-Mercari shipping, I will discount 100 yen. Please comment. If I don't have a box of the right size, I plan to ship them in a waterproof bag and a paper bag. Please refrain from purchasing if you are a nervous person, as these items have been handled by someone else once. To those who understand the above and need them, please consider purchasing them. Thank you.
