Click to Enlarge
.5mm Pentel mechanical pencil lead has excellent lead density formulated with polymer resin bonded to carbon and graphite particles that extend lead life by reducing breakage. They work exceptionally well on paper media with lead hardness ranging from B, the softest, to 4H the hardest. Write smoother and produce lines that resist smearing and fading with Pentel high quality lead. The refills that never need sharpened are packaged 12 leads per tube & value package of 30 HB leads.
