I’d initially planned to launch with a custom-designed pen, but the feedback from early testing suggested that there’s a lot of variety in people’s preferences for writing implements, so instead I opted for a pocket that’s open on both sides, allowing longer pens to be used. It’s pretty versatile and can handle most “normal sized” pens.
My only suggestions for pen selection are:
1) Choose a retractable pen so that the point isn’t exposed when it’s not being used; and
2) You may want to avoid thicker-than-normal pens, unless you intend to stick with that size pen. I’ve carried thicker pens in mine, and it’s a bit tight at first and the leather stretches to accommodate after a few days, but then if you want to revert back to a slimmer pen, it may fit too loosely;
Some pens that I personally like...
1. The Parker Jotter (this is the one I used in the photos/video - https://www.amazon.ca/Parker-Jotter-Stainless-Steel-Ballpoint/dp/B01DJBH2S4)
2. The Pilot G2 Mini (https://www.amazon.com/pilot-mini-retractable-black-pil31210/dp/b00260rq36) – the size is PERFECT, unfortunately they seem to have discontinued it, but if I develop a custom pen for KenzaPad, it will be very similar to this one!
3. The Zebra Telescopic Pen (https://www.amazon.com/Zebra-StylusPen-Telescopic-Ballpoint-Pen/dp/B00NACZB1S) – this is what I’m currently carrying in my KenzaPad…functionally it’s great, in that it collapses down to >4” and fits perfectly, but then telescopes out to a full sized pen for writing. I don’t LOVE the look of it, and it’s a pretty basic ballpoint pen, but hard to beat the functionality.
