These very soft and stretchy rings can be used as a buffer between the bodies of both partners or between the body and the base of a toy. That allows you to easily determine the depth of penetration. The rings can be placed around the penis or a dildo/vibrator. The 4 rings stacked together have a measure 7.5 cm and they are stretchable to a width of 20 cm. The rings can also be used with condoms. Clean the rings after use with water and toy cleaner or mild soap.
