The TWSBI ECO fountain pen boasts an incredible value with its piston filling system and affordable price. Like many other TWSBI fountain pens, this special edition ECO features a crystal clear acrylic barrel so you can see your ink level, and a translucent yellow cap and piston knob. 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. This color is a limited production run.

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 are 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.
