TWSBI ECO Fountain Pen - Irish Green w/ OnyxTWSBI fountain pens are beloved for their clear barrels (sometimes called demonstrators) that allow users to see the ink inside. The pen has an interior ink filling piston system that holds much more ink than a typical fountain pen cartridge. It also allows you to fill your pen up with ink without the use of a converter. Just unscrew the cap at the end of the pen, dip the pen into ink, fill, and screw the cap back on. The TWSBI ECO (for "Economical")

Good Fit but too long
Size: Medium, Color: Army Green
I would give these shirts a 5 star rating if they weren’t so long over the waist, even a medium sized it doesn’t matter way too long

A T-shirt chic? YES!!
Size: X-Large, Color: Wine Red
This is the second one of these shirts I’ve ordered. I don’t wear ties anymore, so I actually wear this mock turtle neck under a blazer, or a sports coat as my father used to call them. I wore a blue one the other evening and I wore it underneath a plaid blazer. Whoever would guess a T-shirt could be quite so chic. It stretches plenty, it’s light and it’s so comfortable. I have two of them now and I’m deciding on a third one.
