Refill lead and eraser set for the Derwent Precision Mechanical Pencil. The graphite leads have a strong point for extended use and minimal breaking. Giving asmooth laydown of graphite, they are ideal for fine detail and cross-hatching techniques.
Each set contains 30 replacement leads in HB and 2B degrees available for both the 0.5mm and 0.7mm lead sizes. Three replacement erasers are also included.
I didn't test them much yet, but they have worked well so far. David Rak (Zahorany, Czech Republic) on 30 Dec 2017
