If you are unsure as to what size to order we have new plastic sizing rings. The plastic sizing rings are round, not oval, but you will get the same accurate measurement. They are the same thickness as the rings that come with the cage. The plastic ring sets are yours to keep. Instructions are included.
The 9 rings range from 1 1/8″ – 2 1/8″.  Please note that the rings you will receive will be black.

Delivery is free within the US, shipping will be added for international orders.

Misplaced paperwork...

Honestly, still the best $25 spent so its not wasted on a poorly sized cage! Although, I kinda misplaced my paperwork, so Im not sure which ring correlates to which size. D: If only there was a link to the sizes online.

these rangs do the job like your mom

Are you reading this? Do you have questions on fitment?

Seriously, if you have an ounce of doubt, get the rings. $25 on rings is better than $300 on a device that's not perfect. This is a big investment, take your time, don't rush it.

Why are you still reading? Order the rings.

Great idea!

I have very sensitive parts due to an unfortunate accident in my past. I feel pain with just about any ball-trapped device on but this kit is allowing me to try the rings for several hours to see how I do throughout the day... including when I'm seated, walking, flaccid, hard, etc. I've thrown numerous non-custom chastity devices away because with time I found them all to be painful. This kit is allowing me to try all sizes so I can optimize my comfort.
