TWSBI Eco T Fountain Pen – Eggplant

A limited-edition Eco T finished in a deep, moody Eggplant purple, this pen shares the Eco's high-capacity piston filler with a slightly more pronounced grip section — the "T" in Eco T stands for a rotary triangular cap and piston-knob design that offers extra structure for the hand, useful for new writers or anyone learning correct pen posture.

The T-Clear demonstrator design lets the piston mechanism and ink level stay visible at all times. A polished stainless steel nib is available in five sizes, and the threaded cap posts securely on the back of the pen.
