These were my late partner's. This is the fetish latex stuff. I know next to nothing about latex or its care. Unsure of actual size When I hold them and make them wobble, they make a rubbery sound. There is a small spot on the inside. I believe it can be removed off but since I don't know the proper ways to care for this material...you may have to try. Most things my partner bought were M/L They were maybe 180 lbs and 6'1"
