Troika Construction Basic Ballpoint Pen

Troika's Multitasking Ballpoint Pen is part of the Construction series. It's a ballpoint pen and a ruler, all in one.

The ballpoint pen takes D1 mini type refills.

As the barrel is made from aluminium and brass, it has a nice substantiality to it, without being overly heavy. The hexagonal barrel won't roll away when not in use and is comfortable to hold when writing.
