Rubber Rings (Crystal Singing Bowls)

Rubber rings are donut shaped and can be placed underneath your singing bowl to provide extra protection and security while playing your bowl. A correctly sized rubber ring will help stop your bowl from slipping around. The friction of rubber can avoid the deviation of the bowl and prevent sound loss. The rubber rings are generally quite thin and require a sturdy, flat surface to be used. Their slim design, however, make these a good option when traveling to play your singing bowl for others. 

Protection and ambiance.
