Get several for those hard to shop for people.
I got one of these for each of several people who I wanted to give something, but not too much. I wanted to have something that wasn't exactly the same for each person, but that I could personalize without knowing too much about the person. This was the perfect thing! I added the person's name, and something about what they like. These are large, have the silver coating on the back, and look more expensive than they are.
