QVC had sold these back when they were doing their 50 state tour. I bought these at their outlet store (price tag still attached) They appear unused as the foam in excellent condition (no indentation as would be case if they had been used). Tiny bit of paint specks and very light scuffs on a couple of them. Comes with instructions.
Simply tilt the object being moved, place these professional furniture sliders under each corner then push or pull the object with ease. The ultra smooth base has a built in dual spring action to apply upward pressure keeping the slide in place during movement.
These are the LARGER Professional sized, each measures approx. 9-3/4" by 6" foam area and 11-1/2" x 7" overall.
