I recommend Contico's sports straw cup, which is not only beautiful, but also very easy to use. You can drink water by pressing and sucking, without screwing the lid of the cup. I also exercise every week. Even if I step on the treadmill, I can pick it up and drink it at any time. I can operate it with one hand, and I can drink it under pressure. It can also be used in daily work and shopping. The most important thing is that I used the same joke of Leo. I recently watched Half Honey and Half Honey.
