Hultafors Dry Marker Refills are 10-lead refills for the Hultafors Dry Marker HDM, in all graphite or a mix of graphite and red and yellow chalk.
The leads come in a small container that clips to a pocket or tool bag, protects the leads, and lets out one lead at a time. The Graphite refill holds 10 graphite leads, made to last and to stand up to moisture. The Graphite and Red-Yellow Chalk refill holds 4 graphite, 3 red chalk and 3 yellow chalk leads.
Hultafors started in 1883, when a young engineer, Karl-Hilmer Johansson Kollén, set up a factory on Folkungagatan in Stockholm to make the folding rule he had invented. The factory moved to Gothenburg and then, in 1907, to the village of Hultafors, between Gothenburg and Borås, where Hultafors still makes folding rules.
