The packet of Mitsubishi Uni Nano Dia Color 0.7 mm Blue leads was delivered today, so of course I immediate emptied my vintage Koh-i-Noor Rapidomatic 0.7 mm #MechanicalPencil to test the new leads, and WOW, are these things *awesome*.
If I'm honest, I think I actually like general writing better with the Nano Dia 0.7 mm Blue than I do with the Emott 0.9 mm blue-black. The color is a more vibrant blue that matches my normal fountain pen ink more closely.
