How to use

Use the TROIKA CONSTRUCTION BASIC as a regular ballpoint pen for writing and sketching. For measurements, align the integrated centimetre or inch ruler with the object or drawing and read the value directly from the pen’s scale; use the 1:20 or 1:50 scales to translate measurements to the corresponding reduced size when sketching. To replace the black D1 refill, pull out the front section of the pen, remove the empty refill and insert a new D1 refill until it clicks into place.

Recommendations

Store the pen in a dry place and avoid strong impacts to preserve the matt aluminium finish and precise ruler markings. Replace the D1 refill with genuine or compatible D1 refills to ensure consistent ink flow and reliable performance.
