TWSBI ECO Rootbeer with Bronze Trim Fountain Pen (Pre-Order)
TWSBI ECO Rootbeer with Bronze Trim Fountain Pen (Pre-Order)
TWSBI went back to transparent material for their latest ECO special edition: Rootbeer + Bronze, pairing a transparent brown/amber acrylic with bronze trim. Pre-orders are now open as of this morning, with pens shipping Thursday, April 30.
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.
A Quick Guide to TWSBI Nib Sizes, per the Manufacturer:
If you write small, go with an EF
For the normal writer, F is the most popular
If you tend to lean on a bigger font, M will be perfect
B is for statements!! Sign a check in B, write a header in B, do some coloring/shading in B
Stub nibs are italic in writing style (have a special card or invitation to write?)
