[Size]: Approximately 8.5cm x 10cm x Height 22.7cm [Capacity]: Approximately 600ml This plastic type is lightweight, making it convenient for children to carry. It has a one-touch open feature and is easy to drink from, which is also a plus. Used a few times and stored at home. There is a faint yellow magic marker stain on the bottom. There are no particularly noticeable scratches or stains, and I think it's generally clean. (Please forgive my amateur assessment.) Thank you very much for looking. Thank you.
