Imara designed these ALL COTTON o-rings especially for smaller bowls or just for those folks who prefer a plant-based o-ring product vs rubber.
Some folks have trouble adjusting their playing pressure to the smaller bowls and we find these COTTON O-rings help stabilize them. Yes, they can be used on any size bowl, but we find them most advantageous on the smaller opaque and frosted bowls.
They were also developed for those who prefer not to use any rubber accessory.
Because we offer to pay your shipping (US Continental ) which exceeds the price of the item, we sell these in packets of 3. You receive 3 Cotton O-rings for this price with free shipping. If you are ordering a bowl or anything else, we are happy to send you 1 only with the rest of your shipment for $6.99 ea.
