As expected, it is a mistake with a simple wash bottle bought at a home center. In the past, when it was early afternoon, we were troubled with liquid bad. Even though I only want to take a lid, when I replenish it, I went to a long straw and the liquid drooled or stuck on my hands. Whether the design of the lid is complicated, only the air comes out even if it is pushed, and it drips with the lid of the lid was trivial. If it is a YK ceremony, you can refill with a refreshing feeling and it is easier to put the straw out to the end than the one in the center of the bottom. Stagnant at the straw destination can get brought down, but worry about temperature change disappears. For those who are concerned about spillage, it is highly recommended.
