How to use

Hold the mechanical pencil as a standard pencil and write or sketch with the HB endless tip; the line is erasable like conventional HB lead. When the tip is worn, remove and replace it with a compatible TROIKA endless writing tip according to the manufacturer’s instructions. Use the printed centimetre/inch ruler and the 1:20 and 1:50 scales on the barrel for quick on-the-spot measurements and scaled sketches.

Recommendations

Store the pencil in a dry place to preserve the matt aluminium finish and avoid exposing it to strong impacts. Use only compatible replacement tips specified by TROIKA to maintain erasability and expected writing length.
