I use the Titleist wrench kit pouch. It fits my medium sized wallet, ring, keys, and watch perfectly and even has a zipper to keep it secure. Then I store it in one of my bag pockets to keep it organized and secure. I don't clip it outside of my bag, just in case it falls off. As for the wrench, I keep in a golf bag pocket or leave it at home. I don't use the wrench much once I have it set just the way I like it.
