Smart container with 10 leads for marking on all types of surfaces. 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; 10 leads in durable graphite or 4 graphite leads and 6 leads in chalk, 3 red and 3 yellow. Refill fits the Hultafors Dry-Marker.
