The Twsbi Eco is a plastic body, steel nib fountain pen that retails for just under $30. The pen is known for its excellent build quality and writing that matches the experience of pens that cost easily twice as much while remaining very affordable. The Eco is a piston-filled pen that does not use a converter or cartridges. As a bonus, the piston mechanism is fully user-serviceable and the pen even includes the tools necessary to remove the piston from the body (for replacement or cleaning).
The Twsbi Eco uses a size 5 steel nib and appears to be of very high quality. It’s a bit undersized and gives the pen a slightly off aesthetic when uncapped, but the rest of the pen is quite handsome with nicely balanced features.
The Twsbi Eco is sold in a number of color variants, which may be considered different models, they include the:
- Eco Black
- Eco Clear
- Eco Pink
- Eco White
- Eco Transparent Blossom
- Eco Transparent Blue
- Eco Transparent Green
Some of these are limited edition pens that are no longer sold. Each of the models are the same but the color of the cap and the end piece are different from the standard, entirely clear Eco.
Note, no ink is sold with the Twsbi Eco, so you’ll have to find your own. The pen only uses a piston filling mechanism so you’ll need a bottle of fountain pen ink, not a cartridge!
