Let's take a look at how the Tombow 8900, Mono Professional, and Mono 100 stack up! Below you can find the handwritten review that I showed in the video, as well as some pictures that show the color of the 8900 a bit more accurately.
PS - sorry for the little bits of dust/fuzz that can be seen sticking to the pencils in the pictures and video. I noticed them while I was editing, but alas, that is the price you pay when you film on beautiful wood floors.
These pencils were given to me as gifts from various sources (you know who you are, and thank you very much again) and I am not being compensated for this post in any way. All opinions above are my own and you are free to disagree with me if you like.
