Periodic Table Pen

It's a cool pen, writes well, great for geek factor. I am not really finding it useful as the print on the periodic table is so tiny. The back does have some useful conversions, laws and constants that are readable. It's a good little pocket guide if you do not need to know the atomic weight/number of an element, and if you are already familiar with the names of the elements. There is something to be said for geek factor, though, That's always really cool.
