ZAMST Thumb Support, Size M For palm, volleyball, basketball, baseball, soccer, all sports, and daily life. Can be used on either hand. Purchased in 2022, used 5 times or less and stored for a long time. Washed by hand before listing. There is a stain (mark) under the tag, but I don't know what it is. I washed it well, but it didn't come off at all, and instead, the printed letters faded, so I stopped. Please understand that it has been stored for a long time and is used, although it has been used only a few times. Please refrain from purchasing if you are nervous, as it is stored at home and inspected by an amateur.
