How to use

Hold the pencil as you would a standard mechanical pencil and write normally; the endless HB tip produces a consistent line without the need for sharpening. If the tip wears out, remove and replace the exchangeable writing tip following the manufacturer’s instructions. Use the printed centimetre/inch ruler and the 1:20 and 1:50 scales on the barrel to take quick measurements or draw to scale.

Recommendations

Store the pencils in a dry place to protect the matt aluminium finish. Replace the writing tip when line quality diminishes. Use erasers suitable for HB lead to avoid surface damage when correcting.
