Just last week, I saw a guy at the hall with a Cuetec joint protector holder. It had a thin piece of plastic between 2 pieces of leather. I wondered if that would work for uniloc, but he didn't know and nobody close by had any uniloc joint protectors to try.
I play in a couple of pool leagues and do not like to leave protectors laying around in case someone walks off with them. I thought about making my own but the material would have to be very thin for the uni-lock threads to grab.
I hate digging though my case pouch at the end of the night looking for the protectors. I had never heard of a holder before but I saw a new Cuetec case that came with one and liked the idea so I thought I would look for one.
