TWSBI ECO Fountain Pen - Irish Green w/ Onyx
The TWSBI ECO fountain pen boasts an incredible value with its piston filling system and affordable price. Like many other TWSBI fountain pens, it features a crystal clear acrylic barrel so you can see your ink level, and an irish green cap and finial. The pen cap has an inner cap to ensure a perfect seal when stored away. It is completed with black onyx trim and a black stainless steel nib.
TWSBI's belief is that it is important to allow the user to disassemble and reassemble the pen and completely experience the traditional aspects of owning and using a fountain pen. These pens also come packaged with a wrench and silicone grease. Neither of these accessories are intended to be used immediately, as they are for long-term care and maintenance. Additionally, please use extra care if you choose to disassemble the nib and feed, as the feed is very fragile.

Customer Reviews
TWSBI emblem fell off finial. Contacted GPC customer service who sent me TWSBI email. They have been very helpful. Was able to glue back on and TWSBI is sending a replacement cap.
The pen is fun colors and performs great. I
I'm very happy I ordered this pen. I ordered the medium nib and am very happy with it. Goulet Pens shipped very fast and I'll definitely will be making more purchases from them.
Oh **** how many pens does one man need, I am learning to write left handed so I can write with two pens, the Goulet's have once again enticed me with another bright and shiny pen, great everyday pen, I am now in pen therapy. I don't think there is any cure!!
This is my second TWSBI ECO with a stub nib, and I got this one because I love green. It's great! Cannot recommend it enough!
