The 7 ring Gates of Hell is presented by Spartacus (manufacturer) and EdenFantasys.

The Gates of Hell with metal rings consist of a series of nickel-plated steel rings connected by a leather strap and they encircle the penis with a stimulating embrace. Slip on the larger end ring first around the base of cock and balls, just as you would a basic cock ring, before sliding the penis through the remaining rings. The first ring is 2" in diameter. The second and third rings are 1.75", the next three are 1.5", and the last one is 1.25". Entire length is about 4".Gates are a hot look as well as fun and effective chastity play devices, however it is recommended not to ware cock rings continuously for longer than 30 minutes at a time.
