About the TWSBI ECO

The TWSBI ECO fountain pen comes with a clear body and various cap and knob color combinations. Both the cap and the knob are hexagon and the cap will post on the end of the barrel of the pen. The cap also has an inner cap to keep the ink fresh when not in use.

Each TWSBI ECO fountain pen comes fitted with a stainless steel nib in an array of sizes. The pen uses a piston filling system for use with bottled fountain pen ink.

While TWSBI isn’t my favorite brand of pens, they’re a great value. I do like the 580ALR nib much better than the ECO, but they’re a great piston starter pen.

So happy with this pen. Love the green color; it looks fantastic with Diamine Apple Glory in it. It writes perfectly - not too wet, not too dry, just right. Love the ink capacity and the transparent barrel so I can watch the ink slosh. Very happy with my purchase.

I love this pen - the color, the weight, the F nib and especially the ink capacity. I also have a purple Eco with a medium nib, which is pretty, but it absolutely gushes ink. I cannot use it at work because it bleeds through most everything. This green pen, on the other hand, looks great, and writes beautifully without gushing all over the cheap office paper I deal with every day. At this price point, I don't have to stress about wera and tear hauling this pen around with me. This is a fantastic every day writer!

Bought this in a stub nib. I absolutely love it. Smooth, nice line variation. Easy to use and economical.

This pen is so easy to fill. It writes like a dream, not catching or dragging on the paper. The pen also does NOT dry out, which is the main reason I purchased it. Now own 3!

Another ECO, joins my ever expanding TWSBI family. What's not to love? PURPLE GOES WITH EVERYTHING. The pen is filled to the brim with Diamine Imperial Purple. A purple pen looks good with purple ink, medium nib skates well across ruled paper, dotted paper, scratch paper and also looks good on my fingers!

I got a fine in the Blossom Red color. This thing is an absolute workhorse. It's my designated grading pen, and it works great for that purpose: it can hold a large amount of ink (my go-to is Waterman Audacious Red), it feels great in the hand, and the nib is wonderfully smooth and never gives me trouble. (It certainly doesn't hurt that this pen elicits more awe than fear from my students!)
