Thank you for viewing! I used these a few times for a few hours in a gym after purchasing them. My child has outgrown them, so I'm passing them on to someone who can use them. They're in great condition with hardly any wear and tear, but please understand that they are used and have been worn by a child. Please purchase only if you understand this. They're mesh and breathable, so they should be great for water play too (´ω`) There is no box, so I will package them with waterproof protection. I will fold the heel slightly and ship them via Yu-Packet Post. If you would like to change to Yu-Packet Plus, I can do so for an additional 300 yen, so please comment to let me know.
