This is the exact one I have, although my golden vibrator attachment broke because I accidentally got it submerged in water.

I honestly would recommend just some cheap cock ring. This thing was overpriced and mostly just for looks. It’s tight enough to count as a c ring. But I would recommend one under 10 dollars because it will do the trick just fine. Heck, even a hairband/rubber band works fine. Just not as fancy.
