I got this Nock.co case as a part of the 2018 PenAddict Kickstarter. This is not something I would have ordered myself, because it is very much outside of what I usually use. But I like it a lot.
The basic concept is a small case with room for two pens and something “business card” sized. This could mean proper business cards or index cards in that size. Something Nock.co sells. So I ordered some of them and started to use this thing.
The Talluah is a must if you are a index card person. And if you like me, are not, I think it can be a interesting addition to for example a pocket sized notebook. There are things where I think Index Cards work better, like capturing stuff or as a blunt instrument when there are a few things you really need to get done. But I prefer using a notebook for lists and stuff like that.
Index Cards and a Talluah have been a good addition to the stuff I carry, and I will continue to use it.
