TWSBI ECO Slate Blue w/ Onyx Fountain PenTWSBI 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")

Poor quality, the book is already falling apart.
Format: Paperback
This is a review on quality of the book NOT the content. I just got the book today and the binding on the cover came off immediately. It’s very poorly made!!!

Description is misleading

The description states that the book includes the access code. That is not true, the access code has been used and publisher is not honoring coffee
