Having a great pen you can rely on no matter where you take it isn't as common as you might think. That's why the reliability of pens like this Tombow Airpress Pen are so amazing. It's a pressure-refill pen that gives you the ability to toss it in your bag and be sure it will write consistently each time you reach for it thanks to the patented pressurized technology it employs. You also get a comfortable rubberized grip and a metal clip to attach it wherever you want it to stay. One click pressurizes the refill for 492 feet of upside-down writing, making it a great choice for folks that work outdoors, write on wet paper, or just need a tough lightweight pen to get their thoughts on paper at a moment's notice.
