Troika's Liliput construction tool pen is - remarkably when you consider its size - a ruler (OK, not a very long one), a capacitive stylus, a slotted screwdriver, a Phillips screwdriver and a ballpoint pen.
With the capacitive stylus, you can doodle on your iPad, iPhone or other electronic devices without it feeling like you're finger-painting.
Twist the front section to retract the refill when not being used for writing. This section also pulls out of the pen for easy refilling when necessary.
The barrel is made from brass so the Construction Mini has a reassuringly solid feel to it, and it's build to last a lifetime!
The hexagonal barrel won't roll away when not in use and is comfortable to hold when writing.
Complete with a black refill and supplied with two spare refills.
