Thank you for viewing! ⭐ This is a water bottle I purchased last month. It seems a little too big for my son, who is slender, so I bought a smaller one. He might be able to use it eventually, but I don't know how many years it will be... It would be a waste if it deteriorated, so I'm offering it now while it's still new (*^^*) To prevent it from opening easily if bumped from the outside, it's the type that you push to open while the lock is down. ※ Sometimes the lock is left open, and you don't notice, and the lid is open and it's soaked～(>_<) But this one, even if you just lower the lock, it will go back up and close the lock. Please push it while it's down⭐ It's new and unused, but I have opened it once. The instruction manual got wrinkled when I took it out and put it back in. There might be some minor scratches on the outer box. If you don't mind the small details, please consider it (*^^*) ※ Sports drinks are OK. #WaterBottle #Kids #LightBlue #Case #NurserySchool #Kindergarten #ElementarySchool #OneTouch #Lock #WithStrap #Name #600ml
