Uni Kuru Toga has a special ordinary pencil - its blade does not become blunt! As you type, the mechanism with built-in bearings spins the ordinary blade, so it wears the same all the time. In this way, the normal line is always the same thickness. You can find the eraser under the normal tail cap.
Roulette has an eye-catching industrial body and the 0.5mm blade is a good middle ground for all ordinary lovers.
