Purchased at the end of winter as a spare. Compared to the ones from Nishimatsuya, these were thicker and easier to use. Because they are thick, I think I won't be able to use them in spring, or I might be able to wear them just at home. They looked very clean at first glance, but since they are underwear, there is a possibility that some areas may not be completely clean. Please refrain from purchasing if you are overly concerned about this.
