DOUBLE WALL WATER BOTTLE 530ML BK

I'm sorry that I only looked at whether it was easy to hold when I bought it, but the lid is hard to close and open. It's not just that it's hard to close, but it's also hard to tell whether it's closed or not. It would have been better if it was made from the same material as the main body, but it's slippery, so it's hard to open. However, it's easy to drink from.

The cooling power is amazing. Even if you put ice in it in the morning, it's still cold in the evening. This series also comes in a larger size!

Easy to wash and feels clean.

This is my second purchase. When I wash it, I have to remove the rubber from the lid, so the knob inevitably deteriorates. It would be great if the lid came with a spare rubber from the start, even if the price went up a little. I've seen products like this from other companies. I think the performance is wonderful for the price.

My husband was looking for something to use at work. He's a cautious person, so he chose this one after considering the price and ease of use at various shops. The lid and body of the one I used to use were both made of the same smooth material. Perhaps because of this, it took a lot of effort to open and close. This one has a rough body, so it's easy to hold and open and close. On top of that, the lid closes tightly and it seems to be spill-proof. My husband makes tea. He cleans it easily with baking soda, etc., and it stays clean.
