TWSBI Diamond 580 Fountain Pen - Iris

Say hello to your new favorite fountain pen.

The TWSBI Diamond is designed to be a classic fountain pen with a piston ink-filling system. No cartridges, no opening up your fountain pen, just seamless filling from a bottle of ink. The translucent body allows for you to see at all times your ink level, and makes for a delightful visual experience depending on the ink color you choose. The pen is easy to disassemble for cleaning, which is best to do between color changes or two to three times a year of regular use. 

Available in two nib sizes, medium and fine.
