Both the Hex-o-matic Pencil and the Hex-o-matic Pen are reminiscent of the kinds of writing instruments your dad would keep in his shirt pocket back in the day. Slick but substantial. The rounded grip texture on each allows you to write comfortably while the upper barrel provides sharp lines to your new go-to writing tool. The pencil takes 0.7mm lead fills and the pen uses Easy Flow 9000 refills when you run out of ink. Toss one in your shirt pocket next to your pack of smokes just like pops did.
