The advanced c-ring is a pure silicone cock ring with an internal diameter of 1.75” designed for use behind the balls. Put it on and it will provide good firmness enhancing tightness. The ring does have some stretch however not very much so you should measure yourself before buying. It has a 3/4 inch wide band that makes the toy comfortable as well as noticeably pushing the balls forward creating more ball-smacking as well as distending the testicles which will enhance orgasm and ejaculation.
If quality, ease of use and body safe products are your forte you’ll likely find the Tantus C-Rings a welcome addition to your collection. The only challenge you’ll have is finding one that suits you’re specific needs and fits comfortably.
I would highly recommend this cock ring to anyone who is wanting to try a different cock ring and that has some experience with cock rings. Also with this cock ring you need to be comfortable playing with yourself otherwise you might not enjoy this cock ring.
