The Tech Tool Pen seems to be a useful accessory for those who need to take notes, measure things, screw/unscrew, and check to see if a something is straight. The multifunctional pen features several tools in one.
The built-in Philips and flat-head screwdrivers are hidden in the pen’s end and you can use the pen to measure things in either inches or centimeters. The ballpoint pen also has a luminous green spirit level to check projects and make sure they’re straight.
Tech Tool pen is described as lightweight and small, having a matte black finish. You can find it online at red5.co.uk for £12.95.
