lead refills
Mechanical pencil cartridges
Lead refills are thin rods of graphite used to replenish mechanical pencils.
Despite the name, they contain no actual lead—the term persists from when graphite was mistakenly identified as a form of lead.
They come in various thicknesses (0.5mm, 0.7mm) and hardness grades: I need to buy some 0.5 lead refills for my pencil.
