The BIG-D cockring by Oxballs is thick super-soft rubbery cockring big enough to wrap around your cock and balls and push all you got up and out for the biggest “D” look and feel. The BIG-D also has gripper flanges on top that squeeze the base of your shaft for even bigger harder erection. The oval shape creates a better ergo fit and it has got extra padding on the back under your taint for more push up and push out the base ring curves in for a slight extra squeeze at the bottom of your nuts and shaft. Using a little lube stretch the ring and tuck your cock and balls through with the top shaft-grippers aiming towards the tip. Made from a stretchy flexTPR it feels firm with its grip but rubbery and comfortable with its stretch.
