The quality of the underwear is particularly good. The manufacturer came to install it in person. The service is really excellent. It is comfortable to use, fits well, melts in the mouth, and is not irritating when washed. Children especially like to eat it, and the elderly also use it. It is very loose and does not pill at all. It is also very clean after washing. Children all love to eat it. The shape is very good, the size is standard, it does not stick to the cup and lasts for a long time.
