A guy I work with considered signing his groomsmen up for the Dollar Shave Club. He ultimately decided on getting each guy a combat gnome (his groomsmen were guys he served with in the Korengal Valley)
I have gotten engraved pocket knives, shot glasses, zippo lighter, beer mugs, flask, and one passed out different Husker stuff. I got a Husker wallet in that one. I use the beer mugs I got all the time, I would say that and pocket knife were the 2 I still use and have.
