0.5mm HB Super-Polymer replacement leads by Faber-Castell, with break-resistant graphite. Exceptionally smooth when used. There are 12 leads in each dispenser and each lead measures approx. 61mm long, hardness HB.
Please note: this 0.5mm version is suitable for only some of Faber-Castell’s mechanical and propelling pencils. Therefore please take care to double-check which lead thickness your pencil uses before ordering. For example, this 0.5mm lead refill is suitable for a few models including the older wooden multi-function writing instruments (but not the metal ones) and some ‘office’ pencil ranges.
