Tombow Mono Zero Eraser

I find them better for longer sessions because their gravity center is next to the lead instead to the back of the pencil. Also, if you're going to use them to make technical drawings, It could be a good idea to get one of those slim erasers like Pentel slim hi-polymer or Tombow Zero (pen eraser, or w/e that's called). They're pretty nice for small details. Also, I'd also get a 0.3 and 0.5 for technical drawing.

Tombow mono zero eraser - Fantastic form factor for really precise erasing, but not the best at actually erasing. 4. Midori 15/30 cm ruler - Nice design and quality feel.

My absolute favorite is the tombow mono one. It’s tiny enough to erase small mistakes, big enough to erase big sections, can be refilled, has a lid to protect the eraser from bumps in the bag (plus feels satisfying to pop onto the body for some reason) and has a very quiet twist mechanism to extend the eraser. I keep trying other erasers but always come back to the mono one. (I’ve had people try to take away my pentel hi-polymer erasers when I let them borrow them though 😂).
