In the wake of the hit “Glow Green” TWSBI Eco, say hello to the ECO “Glow Purple”! This glow-in-the-dark ECO - which glows BLUE! - is the latest release to round out TWSBI’s colorful mid-range line. Pre-orders are now available, and the pen will ship October 31. Collect all the colors, which typically are manufactured for a limited time before they are replaced.

The TWSBI ECO fountain pen is a true workhorse that’s made for everyone, from the beginner who just wants to try out fountain pens, all the way to seasoned fountain pen experts. Taking different design cues from the TWSBI Diamond 580, the ECO features a postable cap for maximum versatility. The pen also has an inner cap to ensure a perfect seal and prevent the nib from drying out when not in use.

Please note that the TWSBI ECO fountain pen is a piston filler, and only accepts bottled ink, sold separately.
