How to use

Hold the pen like a standard ballpoint and write with the black D1 refill. To use the measurement features, align the integrated centimetre/inch ruler or the 1:20 and 1:50 scales with the drawing or object to take quick reference measurements or to scale sketches. To replace the refill, pull out the front part of the pen, remove the old D1 refill and insert a new D1 refill, then reassemble the front part.

Recommendations

For consistent writing performance, use original D1 refills compatible with TROIKA pens. Avoid prolonged exposure to moisture to preserve the matt aluminium finish and wipe the metal parts with a soft, dry cloth.
