3 Blood Flow Restriction (BFR) Cock Rings - one of each size in each pack. 

These Rings were hand-picked for their price to performance. 

I had sets of these last literally years. I end up losing them before they break. 

Best for clamping. The smallest size will fit 4 inches base girth while the largest can accommodate upwards of 8 inches. 

Base girth below 4 inches simply need some padding to make these work. 

For Blood Flow Restriction Therapy, I recommend 3-5 packs so you can get proper occlusion of flow. 

NOTE: THIS PRODUCT IS NOT INTENEDED TO TREAT ANY DIEASE OR CONDITION. BFR CAN EASILY BE OVER DONE. DO NOT EXCEED 10 MINUTE SETS.
