If you love fountain pen ink as much as we do, you'll love and appreciate this handy little refillable J Herbin rollerball pen. It takes standard size fountain pen ink cartridges (such as J Herbin's own fountain pen ink cartridges), which means you have a virtually limitless choice of inks and colours to write with.

That also means that not only are you not tied in to one type of rollerball refill with a limited range of colours, but you stand to save on refills. An absolute gem of a pen.

• Refill with fountain pen ink cartridges
• Use J Herbin's own cartridges or any other brand
• An excellent daily writer
