I am a teacher and I have to carry both my keys and my ID with me.  I go through little keychain wallets like crazy... they all seem to fall apart before too long.  It's been several months and this little guy is still in tip-top shape.  It has a view window for my ID and a slot behind that window to hold a card that you don't want visible.  It has a separate zipper compartment as well where I keep little things like my thumbdrive, money, lipgloss, etc.  The only negative is that what color you get seems to be a gamble...  no way to choose?  I don't know..  the picture had black/gray and I received black and yellow...  Go Steelers.  :)
