Who doesn't love a demonstrator?
I mean seriously, who doesn't love a big honking demonstrator? There's nothing cooler than watching your ink slosh around inside, and the King of Pen is so comfortable in my hand. The Pro Gear is slightly shorter than the 1911 King, and sits a little better in most of my shirt pockets too. Either way, you're going to love the King of Pen if you like big pens!
