10 Vintage Mid Century Industrial Chair

images show 12 glides but this auction is for 10. you will receive 10 of them. Not sure if they have ever been used, I have quite a few of these. inside diameter looks like it will insert into a 1.25" tube.. you get 10 of these. They insert into the bottoms of chairs and stools for use on hard and carpeted surfaces. they help ease sliding and gliding. they have some oxidation from humidity over the years.
