HB graphite pencils Sunset edition made of black lime wood with coloured eraser (yellow, lilac, pink and turquoise). Round shape, lead measures 2.2 mm Ø. HB lead is medium hard, making it suitable for writing and drawing. The lead creates a uniform stroke and is resistant to breakage due to its LPS (Lead Protection System) which strengthens the lead by sticking it to the wood. The wood is sourced from sustainable forests.
