I have a Fossil magnetic money clip that I've had for years. It's slightly larger than the size of a credit card and about half inch thick. Goes in the front pocket and I barely notice it. Shares that pocket with a pen[1] and car key+fob; phone goes in the other front pocket. A Moleskine (of the thin variety) lives in the back pocket. Been pretty happy with that 'set-up'. [1] Either a Bic Atlantis, whose clicking action and writing smoothness I adore, or a Zebra which is a fantastic pocket citizen due to its being metal and its size, and leaves clean, thin lines.
