Comparing TWSBI Fountain Pens

In this video I compare several styles and nib sizes of TWSBI fountain pens. I compare the Diamond 580, Diamond Mini, and Eco models. I continually forget the "I" at the end of TWSBI and then later forget to test each pen with loops, but you should still get the idea--ha ha. I've put links below to where you can get all of the different models. Goulet Pens is not shipping right now, so I've also included amazon and Yoseka Stationery links.
