    This is my first TWSBI, with the ECO Transparent Blue, but the is the firs one that I inked and use. I was surprised by this pen, very high quality nib, soft and pretty wet.

    Easy filling, writing very soft, not scratchy with fine nib.

    I didn’t know what to expect from this pen, heard a lot of praise about it, so I went and ordered one from Appelboom.
    The shipment took longer than expected due to holidays and some other delays, so the wait just made my expectations even higher than before.
    I knew everything is going to be fine once I took it in my hand. I was expecting something plasticky, more on the cheap side, but the material is solid, it feels nice in the hand. The size is good, it fits my large hands, and the medium nib is on the soft spot between F and M. It writes really well. No skipping on cheap paper using various inks. No line variations, pretty stiff, no scratching. A huge ink reserve is a plus for me, a small tube of silicone grease and a tool as well. I love this pen! Affordable, well made, looks great and it’s reliable for everyday use.

    When starting out writing with fountain pens, I was recommended to try a TWSBI Eco. A good, affordable piston filler for starters. I liked the pen so much that I needed to add a black TWSBI to my collection. The pen is a reliable pen, with a good size nib. I take it with me everywhere I go! It has a good ink capacity and is not too heavy so perfect for journaling as well as planning. I highly recommend it!
