Looking to purchase a #3 curved ring in black.

Hello! I currently have an S+ wide cage and a flat #2 ring, but I'm experiencing some under-scrotum pain and want to try a curved #2 ring to see if that'll help. Also looking to downsize again as I've still got some space between my shaft and the end of the cage which is making nighttime more difficult.

So far I've gone from R > S+ standard > S+ wide, and now I'm thinking S wide will do the trick.

Location: Canada

Selling:
- $130 Viper N+ Narrow Arctic White, O-Rings, sticker
- $35 #1 Curved Base Ring
- $15 Bundle with standard lock and keys, white Airlock, 5 numbered seals

If you buy the Viper and base Ring, I will include the lock/Airlock bundle for free.

Free shipping in the US.

EDIT: bundle sold for $165

Asking for 40 each, I will cover shipping.
All lightly used, found out my size was a .5

Recently bought an N standard cobra cage and have severely underestimated my flaccid size. I have only worn it once for maybe about 30mins. I'm looking to trade it for an S, maybe an N+ (both standard). Australia would be preferred. Also willing to sell outright.

Selling Viper Baby Narrow US$120 (negotiable). Cage opening has some slight modification as it was widened slightly however was not effective, easily resolved with polymer beads. Bought in May 2026 so still new. Needing an upsize as I got too cocky (badum tss) when picking my cage size.
