Getting the base ring right is what makes a chastity device actually work day to day, and this two pack gives you the options to get there. Instead of guessing at a single size, you get a large and an XL U-ring, so you can find the one that sits right and keep the other on hand for whenever your fit needs change.
Swapping in a new U-ring is the easy part, it is choosing the right one that matters. Try the large first, and if it feels off, the XL is right there as a backup, no need to order again or wait for a replacement part to show up. Both are built to work with the full CB-X lineup, so whichever device you already own, these rings drop in as intended spare parts rather than a workaround.
This cock cage U-ring two pack comes in black and fits all CB-X chastity device models, so you always have the right ring on hand.
