TWSBI fountain pens are loved for their high quality and affordability, offering advanced filling mechanisms normally reserved for much more expensive fountain pens. The Diamond Mini features a modern, eye-catching design, with a transparent body that shows off the pen's inner workings. About one inch shorter than the Diamond 580
, the Mini is conveniently pocket sized, with a cap that can be screwed onto the back end of the barrel when the pen is being used. Its faceted barrel catches light and makes your ink shine, and it also helps keep the pen from rolling away. The piston filling mechanism is easily operated by twisting the knob at the end of the barrel counter-clockwise to extend the piston, submerging the nib in ink, then screwing the knob tight to retract the piston, drawing ink into the pen straight from the bottle—no need for cartridges or a converter! Be careful, operating the piston while ink is in the pen will cause ink to leak out of the pen.
In keeping with their philosophy of promoting the traditional experience of using a fountain pen, TWSBI has designed this pen to be completely self-serviceable. It comes with a wrench and a vial of silicone grease you can use for at-home maintenance.
This pen can be refilled from any fountain pen ink bottle, but for clean and easy refilling, try a TWSBI Diamond 50 Ink Bottle, which has a special component designed specifically for refilling TWSBI Diamond fountain pens.
The pen comes in an attractive clear plastic case with a clean, modern design.
For protection, the plastic case is packaged in a cardboard box. This cardboard box is fragile and may get crumpled during shipping.
This pen only uses bottled ink, which is not included with this pen. Check out our collection of bottled fountain pen inks here!
