For more than half a century, TWSBI have been crafting pens for renowned global brands, an experience that inspired them to launch their own brand. As experts in the field of pens, their mission revolves around creating the highest quality pens while maintaining affordability.

The TWSBI Diamond Mini is the smaller, more portable version of the 580. A timeless fountain pen, boasting a piston ink-filling system, so that you get maximum ink capacity. Combining classic mechanics with a contemporary aesthetic, this pen is the perfect one for having in your bag and on the go. The Diamond Mini is designed with full functionality, with all detachable parts to enable you to completely disassemble the pen. The barrel of the pen is clear, so you can see the clever inner workings of the pen, as well as easily see your current ink level and colour. The cap screws in place on the end of the pen for secure posting while writing, as well as a clever internal collar to stop you from over-tightening the lid.

Remember - with these pens you won't need cartridges, instead select from our range of bottle fountain pen inks to fill the pen.
