ZAMST knee support ZK-3, for both left and right knees, for all sports and daily life, size 3L. Purchased on Amazon in 2022, I believe I used it about 5 times. I washed it by hand before listing it. There are marks from the clothespins. I don't think they will disappear completely, but please be aware of this. Please understand that this is a used item. Please refrain from purchasing if you are nervous about this item, as it has been stored at home and inspected by an amateur.
