There Are Pandas, and Then There Are Pandas.
And this isn't either of them! The Pandas we're talking about here, are watches, not bears. And what got me thinking about them (again) was a link posted this morning by @cm.rook who pointed a few of us to the very attractive (and not terribly priced) Yema "Rallygraph" Panda which, in it's most traditional arrangement, looks like the one on the left, but can also be had in the version on the right: The model on the left is a true Panda, while the model on the right is called a reverse Panda. The reason for that distinction is clear--Panda bears, only come in the first arrangement. Now at this point, everyone should be thinking about the most well-know Panda, The Rolex Panda, which is actually a Daytona, and among Rolex Daytonas, the most famous of which is the Paul Newman Daytona, which was famous first, because it was Paul's, and second because it sold at auction for $17.8 million (US Dollars).

To answer your question, when I was in school I gravitated toward technical pens loaded with inks designed for drafting. I've still got a set of Koh-I-Noor pens with some ink still left in the original bottle. The ink dries incredibly quickly, and once dried, is pretty impervious. For drafting, technical illustration, or inking pencil drawings, it means you can erase the pencil lines after inking without smudging anything. For a leftie like me, it means by the time my hand drags over the ink, everything is already dry so nothing smudges.
But they're not without their problems. I live at 2,500' above sea level, but routinely work at 14,000'. The pressure change is enough to make these pens dump ink everywhere. The same thing happens if you take them on an airplane without emptying and cleaning them first. These days I mostly use whatever pen I have in my bag, and smudge away. :/
