Jacques Herbin's Twisted Glass Dip Pens are beautifully made from coloured glass, each one individually hand-crafted and entirely unique. Tiny grooves on the nib ensure several lines of writing before having to dip again.

Glass pens are often purchased for decorative reasons, unsurprisingly given their beautiful colours and variations, but these are also great to use. While glass might not be our first thought when we think of writing, these are a surprisingly comfortable and enjoyable tool to write with.

Best for use with fountain pen ink. Also suitable for use with calligraphy ink but some thicker inks might need watering down for use on the dip pen - if the ink is too thick it won't flow and will blob on the page instead.

Sharpen nib with fine sandpaper (Herbin recommend grade 400).
