The Eco is the 6th model in TWSBI’s lineup available in two colors, white or black, and was designed with the intention of being as economical as possible. Currently, several models sell for $50, which is already a pretty affordable price point. Beating that price by any margin while maintaining any kind of quality would surely be a challenge.
TWSBI has released the Eco for an impressive $28.99 and, from what I can tell, have managed to create a quality pen in the process!
To achieve their goal, TWSBI has removed as much metal from the pen as possible and simplified their design. The only metal in the pen is the nib, the bap band, and clip. There’s no metal accent bands or collar for the piston unit, and if you count the cap assembly as one part, then there’s only 10 pieces to the entire pen with the major change being the section and barrel are now one solid piece!
