Title: Work Perfectly
Review: These disks work perfectly. The larger disk is quite large, the undersides of both sized discs are hard plastic, and the lips cup upward slightly. The orange section is cushiony yet rugged. I slipped the larger discs under a very troublesome piece of furniture I have to move regularly over carpet to vacuum behind, and it slid perfectly. I left the discs there, as they are hidden, and it slides great everytime I move this piece. Very inexpensive, yet great quality. They come in a very nice box as the companys' packaging, and I'm glad I bought them.
