Well I don’t know how I found them but I stumbled across them. I’ve got a couple dozen plus broken ones that you use for the ends.

I looked at the classic billiards site and they seem to be the same.
If you have new ones from them I would just wipe them with a lotion or silicone and twist them through the holes.
Sounds good. Thanks for looking!
