Wiring? Try the 8-Color Crayon “PENCO”

Lately I’ve been working with wiring pretty often.
Every single time, I write it all down on paper.
There’s B/W and W/B,
and O/B and O/BL and so on—I keep making mistakes writing them down and reading them back.
It means extra checking, which is a pain.
Isn’t there an easier way?
I figured if I could identify wiring colors by both text and color, that would be easier. So I thought…
But buying all those markers individually is a hassle and they’re hard to use.
So I searched Google for an all-in-one solution,
and I found it!
 

 
“PENCO”—a Japanese company.
It has 8 colors inside, and you twist it around to pick your color!
Then you push to extend it and pull to retract it.
 

 
This should cut down on mistakes…
