The Polar Pen is the first pen made entirely of magnets. If you are anything like us, we like fiddling with pens. The Polar Pen takes fiddling to a whole new level. You can waste some serious time playing with the extremely strong magnets that make up the Polar Pen. Check the video below to see the “revolver” and the “spring”. The Polar Pen is compatible with a couple different refills but the Uni-ball Signo UM-1 is the recommended refill. You can pick yours up by clicking the link below. Yeah you can get a cheaper knock off on Amazon but we can guarantee it won’t be the same quality.
