We use synthetic rubber.

Abrasion-resisting, hard and firm, they feel comfortable and the smart design makes them more creative.

Top notch and well made with the metal insert, they will slide without scratching the wall and floor.

Also, you can mount them firmly without worrying about crushing the rubber.

Good for a guitar amp or furniture and so on.
