TWSBI - ECO T
The 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 solid black cap. The pen cap has an inner cap to insure 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 a hexagon.
TWSBI's belief is that it is important to allow the user to disassemble and reassemble the pen and completely experience the traditional aspects of owning and using a fountain pen. These pens also come packaged with a wrench and silicone grease. Neither of these accessories is intended to be used immediately, as they are for long-term care and maintenance. Additionally, please use extra care if you choose to disassemble the nib and feed, as the feed is very fragile.
