This is a great little pen. The Zebra F 301 Compact pen is less than 4″ with the pen closed, converting into a full size pen when opened. I pretty much stopped carrying pen’s two years ago simply because I kept losing them. I have had this pen for two weeks now and it’s never been misplaced or missing. This is also due in part because it conveniently clips horizontally along the bottom of my Slimmy and is exactly the same length. It’s just one more thing that I do not have to involve my psyche. Lastly, the pen actually writes pretty darn well 
We get asked this all the time. It’s almost the wrong question. There is no maximum per se, but I wouldn’t plan on trying to keep more than 15 cards in the Slimmy. At that point you might as well have a big old George Costanza wallet anyway because you loose the sleek nature of the Slimmy. You also wouldn’t want that much in your front pocket. American Express actually circulated a warning this summer saying that men carry too much in their wallets leaving them very exposed to theft and then identity theft.
I used to be an 18-card, 2-months-of-receipts, lots-of-extraneous-crap guy with a big butt brick. I would use the Slimmy when I was going out and just grab the essentials, but eventually I never went back. I still have the old wallet full of loyalty cards from burrito stands and what not, but I keep a pretty trim Slimmy that has everything I need everyday and is small enough that you can’t tell I have it unless you frisk me.
I keep 4 bank/credit cards, license, registration, health insurance card, car insurance card, 1 to 5 business cards, and as many as 10 bills and a days worth of receipts.
Slimmy reminds you to take stuff out of your wallet. It’s so appealingly sleek when it has only the necessities in it. Once you have a few extra receipts dangling out, you remember to file them away. It reinforces discipline.
