A couple of weeks ago I read Anthony Sculimbrene"s Everyday Commentary review of the Twsbi Eco. At $30, it was a guilt free impulse purchase. I have always wanted a clear 'demonstrator' pen and my favorite pens are piston fill like the Eco- I have not used a cartridge in decades. Being 64, clear Bic pens were relatively new and many kids still used cheap fountain pens. Most of these pens wrote terribly and where dropped in favor of ball points. When I was working in a large law firm after graduating and decided to go back to fountain pens, I could afford better pens, bought them and never looked back. I probably have 9 or 10 good fountain pens, Pelikans, Parkers (new and vintage), Waterman, Pilot, a Mont Blanc and a Conklin. My favorite pens are the Pelikans. With this background, I am blown away by how well the Eco writes, fills, feels and looks. I think it is worth 3x the price. The medium nib Eco lays down a thicker line than the Pelikan medium and is a bit stiffer, but with bottle of Pilot ink, this is one hell of a great writing tool at a great price. At this price I may buy another in a fine nib. Do you want to try a fountain pen for the first time? Are you hesitant to spend hundreds on an experiment or just hesitant to spend hundreds on a pen period? Get an Eco and buy it via the link on Tony's web site.
