They are bulky open weave. Made for me in the late 80s but I never used them because shorter leg warmers were more on trend at the time! So these are unused. They have been in a drawer for years and if you look closely you may see a faint area of soiling on one (can't imagine how THAT happened).
I put tape measure in one photo so you can see how long they are.
