- Smooth steady ink flow
- Distinct line variances
- EF particularly fine
The TWSBI ECO fountain pen offers a superior quality piston-fill fountain pen at a wallet friendly price. Distinctive styling is apparent through the hexagonal cap and matching piston twist tip which meld seamlessly into the cylindrical barrel and gently tapered grip section. The demonstrator style transparent body allows you to see the piston fill workings and remaining ink levels, whilst a rubber O-ring, between the barrel and twist-off cap, ensures a secure, sealed closure, preventing leakage and drying.
All TWSBI fountain pens can be disassembled for cleaning and maintenance. TWSBI includes the tools to do so, but recommend this is only carried out by experienced fountain pen users. This should only be carried out as part of long term servicing of the pen; it will not need to be done straight away. All disassembly is carried out at the owners risk!

The TWSBI Eco is really great! The nib has a very good flow, the M nib is just the right thickness, and the ergonomics of the entire pen are wonderful for my medium-sized female hands. I can 100% recommend TWSBI Eco and TWSBI Diamond!

A great every day pen. I bought it for drawing and it holds a lot of ink (Which you can see) and feels good in the hand.

The pen is lovely to hold, it's weight is just right and inkflow is very smooth.

This Twsbi Eco has "China" written on the cap, and it is simply not the same quality as the two other "Taiwan" Ecos I own : this nib feels like a M when it's supposed to be an F, and the ink flows way too fast. As a result, the words on the page look bloated. I am very disappointed with the Twsbi Eco.
