Faber-Castell 0.7mm 2B Super Polymer Premium Mechanical Pencil Lead Refills - 96 Leads (4 Tubes x 24) - Dark, Smooth & Strong for Writing, Sketching & Technical Drawing - Compatible with All 0.7mm Mechanical Pencils

I didn't expect pencil lead to be so satisfying! These are smooth like butter. No scratchiness at all. This really is one of the best art supplies I've purchased. I'm sure they're great for writing as well. These feel like the leads that came with my rotring pencil, except these are darker, which is what I prefer.
