Winnie the Pooh design 300ml children's water bottle Although it is made of plastic, it is relatively strong, and you can carry it cold by putting a frozen stick (with a dedicated ice stick bottle) inside the water bottle. The ice stick can be inserted into the inner lid and will not wobble. With a height of 20cm and a thickness of just under 9cm, it can also be put into small bags. The cap has a secure gasket, so there is no need to worry about leaks. I think it's convenient to take it with you for short outings(^^)⭐︎ The heat resistance temperature is unknown. I will include a plastic bottle as a bonus! Thank you for looking.
