Warm reminder: This is an ultra-thin and ultra-light 80-count Lansing modal. The high-count modal has a very fine and soft hand feel and better breathability. However, due to the thin and soft fabric, it cannot be machine washed and there is a possibility of it being scratched during machine washing. So please be more diligent, dear friends! Machine washing not only damages your underwear but also makes it easy for bacteria to breed. Try to change your underwear every two to three months. Wearing it for too long can also breed bacteria and affect your health.
