My collection so far
The Uni Kuru Toga metals are my favorite, and Kuru Togas are my go-tos in most cases. But the Tombow Monograph is a close second, as is the Rotring, and I prefer the twist eraser to the cap on the Kuru Togas. I don't have a higher end Rotring just yet but the 500 is a great daily driver at my desk. The Faber Castell Grip Plusses (thicker blue and green towards the right) and Bic Velocity (orange far left) are for all around use, to throw in a pocket or bag. Some of the others are cheaper ones from Muji (clear), Pentel (on the lefthand side), and Staedtler, but they still hold up. I write a lot for work and tend to go through a few cheaper mechanical pencils per year, with the clip breaking off or grip getting grubby, but this is just for fun. I also threw in an Apple Pencil and two 'forever' pencils on the right, but the lead on those tends to be too hard for my taste.
