I received this as a gift, but I'm not going to use it, so I'm selling it! It opens and closes with Velcro, so I think it's easy for children to use♪ Photo 4 says 3-6 years old, but personally, I think it's for 2-3 year olds! For those who love Snoopy♪ It's new and unused, but it's been stored at home, so please refrain from purchasing if you are nervous about this! The price is 2800 yen + tax♪
