Hultafors Refill can be attached with a clip in the pocket or tool bag. The design of the container protects the leads during transport and only ejects one lead at a time. The refill is available in two combinations. HRD G offers 10 leads in durable graphite, Hultafors HRD GRY offers 4 graphite leads and 6 leads in chalk (3 red and 3 yellow). Refills fit the Hultafors Dry-Marker. | Hultafors Tools Dry Marker Refill Graphite in Grey
