It says 33cm, but the actual size is 34.5cm. Perhaps the way of measuring is different. The height is 31cm. I will include the lid, but it might be a little big, so please consider it as a bonus. I used it for about a year, and I left water in it overnight, but there were no leaks. There are already scratches, so I will ship it with simple packaging without wrapping it in bubble wrap. Thank you.
