TWSBI ECO Fountain Pen - Cosmos with Onyx Trim macassar The Diamine Black Edition SleighTWSBI ECO fountain pens have stainless steel nibs and use a piston filling system. The barrels are clear so you can see the amount of ink and the cap includes an inner cap that provides a perfect seal when the pen is not in use. Note: Please take care if removing adding the nib as it is very fragile. **Every pen will be unique in pattern variation, as these patterns are completely random during the injection process and cannot be chosen.
