TWSBI Diamond 580 IRIS Fountain pen

Ink pens have always been a classic choice for people who love writing and enjoy the process. Every writer has their preferences, but one brand has won the hearts of many with its products.

The TWSBI Diamond 580 IRIS Fountain Pen is another example of why we love this brand. The pen is made of transparent polycarbonate, giving you a clear view of your ink level. The piston-filling mechanism allows you to fill your pen effortlessly, making it a pleasure.

But what sets this model apart is its beautiful rainbow-effect stainless steel nib. It adds a touch of elegance and uniqueness to your handwriting, making it truly special. It's compatible with piston-fill only and comes in Medium nib size only.
