By attaching it to the bottom of your favorite water bottle, you can prevent paint peeling and scratches. It is made of silicone, so it can be hand-washed. It is also easy to attach. When placed on a desk or floor, the silicone absorbs shock, making it quiet. If the diameter matches, it can also be used for bottle tumblers and travel mugs. It can be used with manufacturers such as Thermos, Tiger, Zojirushi, and T-fal.
