Zojirushi's cold and warm insulation makes your mouth feel good. It has great performance, is light, and this design is so pretty~ It's light and I bought it at a good price~~

The 500mm on the left feels smaller. The 400mm on the right makes an annoying sound when the lid is closed, but overall I am satisfied with everything.

I put ice and water in it, but 10 hours later there was still ice. It has a handle so it's easy to move around, and the wide opening makes it easy to clean. It is a 500ml tumbler and is similar in size to a 500ml water bottle.
