ダブルペン矢筒ペンホルダー中型ノートブック用

I use this everyday. It’s my tool belt- my tools are a fine line Sharpie and a liquid Sharpie highlighter to mark up my study Bible. It is amazingly well built and I love it. I cannot recommend this highly enough!

I've been using one of these for about ten years now, and just purchased another to reduce the swapping I was doing. I still like note books as the notes I take can be more flexible (words, diagrams, quick tables, etc). The 10 year (10+ years?) old one has aged perfectly. I actually prefer it more now as the strap is looser and easier to get off and on. The new one looks as well built (I picked up the newer one in the photo just before their site change). I carry a custom fisher space pen and a pentel Kerry mechanical pencil. I generally use moleskine and rite-in-rain notebooks. A nice side feature of the strap is that for the rite-in-rain (which don't have an internal pocket), I can use the strap to hold external papers / notes instead of leaving them loose.
Really just a wonderfully well made tool that ages perfectly. Stop thinking about it and just buy it.

I first saw a Quiver on a coworker's notebook. As soon as mine arrived I understood why she was so obsessed with it. I am a very critical person but these are just about perfect. Nothing else I've tried or seen comes close. They hold on to the notebook just right, the pocket is perfectly sized, the leather just gets better over time... I only wish I had a reason to own more than the two I already own.
