ECO Transparent Blue Fountain Pen F nib

Great pen. I love the large tank and it is a smooth writer. I never have any trouble getting the ink to flow even if it ends up sitting for a week or two.

One of the best fountain pens I have found as a daily writer. I have always carry a fountain pen as my daily pen because I have to document my activities in great detail. Of course, like most of us I run out of ink at the most inappropriate times. But now, I no longer have to stick cartridges in my truck, wife's car, my carry bag, my work desk, coat pockets, or other places around my work and home to ensure I have a ink cartridge ready when I need one. This pen holds a tremendous amount of ink with the ink level clearly shown since the barrel is clear. I ordered my ECO with a fine nib which seems to lean more towards a medium. A smooth writer on a variety of paper forms I complete each day. If you are looking for a workhorse pen you can use everyday I would recommend you give the ECO a try, I think its the best and most cost effective pen around if you write a lot during the day.

This is an extremely solid fountain pen for the price. It is easy to load up a lot of ink and writes very smoothly. The cap stays on nicely since it is a twist on and posts on the back of the pen as well.

TWSBI has a different look but after 18 months with this pen traveling the world in a backpack I have to give a review - it has never leaked nor run dry, so that makes it a fantastic travel pen. Works great and reliably great.

Works very well. Instructions are minimal, but YouTube videos were available. Plastic construction, but seems study. Great value for ease of writing and being refillable.

I don’t write many reviews, especially good ones. I’ve had my blue Eco for a yr or so now. The Twisbi Eco is an amazing fountain pen. I have quite a few fountain pens, Parker, Waterman, Namiki, and sure the nib on this one isn’t an 18k gold nib, but… this thing is as reliable as a rollerball. The seal on the pen is just amazing. I can put this pen down literally for weeks, pick it up and it writes, it doesn’t dry out and it doesn’t get ink on the grip even traveling. If Twisbi would make this mechanism in resin with a gold nib they could just take my money.

Admittedly, I have too many fountain pens. This was recommended to me by another fountain pen person and she was right - it's easy-writing and fun to use. Mine has blue accents and I filled it with blue ink, so it looks good (and collected some compliments).

I finally understand the hype. For the price, this should be the standard for a good pen with a top quality nib that can compete with any higher priced fountain pen.

Desde el primer momento escribe como si la llevaras usando toda la vida, muy buena relación calidad precio, llegó a tiempo. Compra perfecta

Great pen, lovely colour, huge ink container and fab to see the ink through the barrel. Love it!

Una penna davvero ottima. A partire dalla confezione si nota che è costruita con materiali di buona qualità. La penna poi è con caricamento a stantuffo, che per il prezzo è davvero una rarità. Il pennino scorre benissimo. Insomma, davvero un ottimo rapporto qualità-prezzo. Arrivata nei tempi senza nessun problema.

Fantastic fountain pen. Large reservoir of ink, end capable if needed, smooth writing and not a drop of ink spilled yet.

I used lamy and waterman earlier. This nib is somewhere between Lamy fine & medium nibs, the most perfect for my handwriting. I am a doctor & this literally glides even on the thinnest hospital papers. More smooth & looks amazing. Not going back to lamy !
