Moleskin notebooks are great because they're simple, handsome, compact, and wonderfully pretentious. Along with them, Moleskine also makes a pretty classy line of pens.
Its Rubber Click Roller Pen ($11) is designed specifically to match your journal. Made out of the same familiar black material, it has a rectangular shape and a little rubber clip so you can attach it to your diary. Pretty handy, because we all know the pain of rifling through your things in search of something to write with. Next time you're scrambling you won't be left with that chewed-up Hello Kitty pen you swiped from a gas station. [Uncrate]
