rite in the rain index card wallet
Since switching over from paper journals (and legal pads and whiteboards) to the reMarkable 2, I've shifted away from my still-beloved fountain pens (that the EMR I'm using is Lamy's EMR variation on their AL-Star fountain pen is a big help) to pencils for my non-digital notetakings and processings.
As such, I've been seeking a pocket notebook that both a.) could be used both during running and general leavings of the house, and, b.) didn't overstuff my already-stuffed pockets (read: Herbie the insulin pump). Happily, the Rite In The Rain Index Card Wallet, packed with their waterproof index cards and scribbled upon with my Kaweco Special S 0.7mm mechanical pencil, more than satisfies those requirements.
One hiccup, though: the RIR cards are (more than) a bit expensive - $16-$20 per pack of 100 - so I'm going to do a test with one of the regular, $2/pack of 100 cards that I've got lying all over the place to see if the waterproof part really makes a difference: while I know full well that it does with paper, I'm not certain it matters with cards, especially since I'm using pencil.
Either way, very happy to have solved this particular long-standing quandary.
