Want to use a smaller toy or a toy with a smaller base? Sensitive to the hardness of the metal O ring that holds the toy in place? Swap it out for one (or two) of these rubber O rings!

KinkLab's three-pack of Rubber C-Rings contains three rubber O-rings in diameters of 1.5", 1.75", and 2" and can be swapped in for the O ring your harness comes with. They are made from firm but flexible nitrile rubber — a synthetic rubber that’s safer for many with latex allergies and which can be used with any kind of lube. Yay!
