I’m very particular about my writing tools, especially pens. Although I’m particular, I’m not very loyal. I go through phases a couple of years at a time. Before the current phase, I used to go through multi-colored pens.
Now, I’m all about smooth Japanese pens that you can only get on Amazon with about two week wait period. My current favorites are Uni-ball Signo RT1 and Zebra Sarasa Clip 0.3.
