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!

Beautiful Pen. Easy to fill, and a large reservoir for ink compared to converters or even cartridges in many cases. I like the shorter size. The pen feels compact but elegant. Cap definitely needs to be posted in order to fit comfortably in my hand when writing, and there are threads provided so the cap can screw on tightly when posted. (There are also threads when screwing on the cap when not in use.) I dock one star because the EF nib is just slightly scratchy sometimes, which I understand can be a preference for some. I wish the nib was buttery smooth, and because I write small, I definitely want that smoothness in an extra fine nib.

I just upgraded my TWSBI Eco to the TWSBI Diamond Mini Clear! It is such a beautiful pen that I can't stop looking at it! I love the gorgeous faceted ink window and its sleek design. I read that when capped, the regular (non-mini) pen is a bit long, so I opted for the mini size which sits perfectly in my hand. The only drawback, which is pretty vital, is the fact that this extra fine nib writes like a medium nib. I like to write small, so the unexpected thicker stroke was a disappointment. While visually stunning, the nib quality was a let down.

A wonderful workhorse of a pen that is always ready, never skips, and writes as smooth as silk. I especially enjoy the construction of the pen, and that TWSBI supplies each pen with a wrench and a small bottle of silicone grease to maintain it. The weight is perfect when posted, and the threaded posting of the cap insures that it won't get lost. This pen won't feel like you're holding a railroad spike after an hour of writing, and I am amazed at how long a single fill of Diamine blueblack ink lasts in it. There are prettier pens out there, but pretty isn't what gets the writing done. This pen means business, it's easy to fill and maintain, and you'll always know how much ink you have on hand for the job.

Outstanding Quality! I now own 4 different TWSBI fountain pens with various nib sizes and even went out of my way to acquire the 1.5 nib direct from the manufacturer. Their performance and design are unmatched and are definitely some of the favorites in my collection.
