I use these protectors on my bows, but they might not fit just every bow. I have a Samick Red Stag and the tips of the limbs are too wide. If these you are asking about are sort of plasticky and not super flexible, they are the ones that can be too narrow for the limb tip. There is another that eRivers sells that is somewhat softer and more flexible. I bought one of those for my Red Stag.
Sorry I could not be more definitive. I am at work right now and my equipment is at home.
Good luck in your efforts.
PS: I know that money and sometimes time can be an issue, but this sort of tip protector is not very expensive. If cost is not a worry, you might consider ordering a couple different types. When you get them try the most likely candidate and send the other back unopened.
