TWSBI ECO Fountain Pen, Black, Fine Nib
- Source: eBay
Purchased it new to try out the TWSBI. The pen works very well but I have too many pens, so selling this off. It is the black color, demonstrator pen, with a Fine nib that writes very smoothly. No cracks or other marks, and the piston is smooth. Everything except for the silicone grease will be included with the sale.
