The TWSBI ECO-T 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 a clear cap. The pen cap has an inner cap to ensure a perfect seal when stored away. It is completed with silver trim and a silver stainless steel nib. The ECO-T differs from the ECO in that it has a triangular grip section for ease of holding the pen, and triangular shaped cap and piston knob instead of hexagon.
