I bought this for my elementary school-aged son, but he didn't like it because it was too big, so he used it once and then I stored it. I have disinfected it before listing it. I don't seem to have a chance to use it, so I'm offering it to someone who will. ● Resin "Protect Armor" to guard the body from impact ● Seamless lid that doesn't require disassembly of the packing! ● Interior coating of the main body that can be washed quickly ● Sports drinks OK! Purchase price: 5,808 yen (tax included)
