I’m looking for something to replace my s-biner. The thing I like about the s-biner is how thin it is. It’s very easy to slip it around my belt loop. What I dislike is that my keys keep falling off of it and into my pocket. I put some heat shrink on it, but I’m just not happy with that as a permanent solution. I don’t need something with two openings, but I’m not opposed to it. I also don’t need one that costs hundreds of dollars and makes margaritas and functions as brass knuckles. I just need to hang keys on my belt loop. Any suggestions?
