Still working on the Kyoto post I promised, so this week, a back-up post.
I introduced one of my work pen cases in December. Here's my other work pen case at my other workplace.
It's pretty much the same thing as the other pen case: Frixions in 0.7 Black, Green, Purple, Light Green, Light Blue, Pink, and Orange, 0.5 Blue and Red, a set of Frixion highlighters, and a Frixion eraser. I've noted what I use each pen for in the other post.
The difference is that since I teach kids more often at this workplace so I also have a set of Tombow Playcolors and a set of Sakura Coupy-Pencils so I can draw my stick figures and other awesome (?) drawings. See below.
It took me a relatively long time to buy a second set; I was carrying one around with me all the time, but somewhere along the way, I got tired of carrying 9 pens and 6 highlighters around. So I bit the bullet (as if it were that painful for me) and bought a complete second set of pens. It was the right choice because of the sheer number of pens.
