Troika Multitasking Ballpoint Pen Concrete Matt Grey/Silver

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

With the replaceable capacitive stylus, you can doodle on your iPad without it feeling like you're finger-painting.

A ruler is one of those things that's rarely around when you need it, and this one is marked in centimetres and inches, with 1:20m and 1:50m scale.

The ballpoint pen takes a widely-available D1 mini type refills.

As the barrel is made from concrete and aluminium, it has a nice substantiality to it. The hexagonal barrel won't roll away when not in use and is comfortable to hold when writing.
