Maternity Tights M〜L Denier is not indicated, so it's unknown, but the thickness is not too thick nor too thin, making it easy to use. I bought these for work, but I hardly wore them and only washed them, so they are in good condition. However, please refrain from purchasing if you are very particular. I didn't see any snags. I have home-laundered them, so due to the nature of the fabric, there are some areas with slight pilling, but it's to the extent that it can be removed by hand. Please check the photos and only purchase if you agree.
