TantusSex/Adult Toys Silicone O-Ring Harness Set - 100% Ultra-Premium Silicone Includes 6 Different Sizes for BDSM Toy Collection - Onyx

These rings are way too stretchy. The toy that you try to restrain with them always flops out. At least they're silicone, but they're definitely not the right firmness of silicone for this task.

This is like a rubber band and doesn't hold anything. This needs to be thicker farmer and have some structure to it. I feel like I'm using the ring from a paint can. Far too flexible.

I got this for the larger sized rings that would fit the Colossus Dildo, the Black Balled, Bam, etc., for my lady to use on me during our play time. The rings will fit over these with no problem. She has some difficulty holding these monsters up until she gets it started on its way, but that has nothing to do with the rings. They do exactly what they're supposed to do, which is enabling you to strap it on and stick it in!

Probably good for using as a cock ring but too stretchy to use with a strap on dildo. My dildo went flinging out of my harness. Hot.

Bought with the intent of using on the harness we got for my wifey to use on her g/f but ended up never using them.Would be better if it came with good photo examples of using these with the toys and harnesses.

Bigger toys need bigger rings. This does the trick nicely. Covers all the sizes I will ever need and more.

Great variety of sizes. No slippage and nicely stretchy without being too stretchy.

Do not plan on using these on the suction cup / harness base. they are way to stretchy. I would say they stretch 3x the original size. Unless you like stopping to pick up your dong off the floor and clean it again. as for slipping it over the dong (if it has balls) it may work OK. We tried to use it with a UR3 dong and I am concerned that the straps (Nylon Strap on my harness) would damage a costly dong. I red before buying that they are flexible but they left out the part where they are to stretchy to use as a conventional Harness ring for harness compatible dongs.
