Basix is represented here by hardware rather than a toy: a universal harness from the Rubber Works collection, supplied with three interchangeable rings rather than a single fixed opening. Those rings measure roughly 3.2, 4.2 and 5.2 cm across, which is the detail that decides whether a harness is actually universal or only nominally so. Swapping the ring is how one harness accommodates a slim dildo one evening and a thicker one the next, and it is why buying the harness and the toy separately usually works out better than buying a set. Nothing here vibrates; this is the frame, and what goes through it is your choice. The strap-on and harness shelves hold both the vibrating alternatives and the toys to pair with this one.
