A fountain pen is a writing instrument in the form of a pen that transfers ink to paper using a metal nib. The ink flows from an ink cartridge (converter or ink cartridge) through capillary action through a narrow slit onto the paper. The types of cartridge in our pens can be replaced at any time.

A rollerball pen or roller pen is a writing instrument that delivers water-based ink via a writing ball, similar to a ballpoint pen. The ink is thinner than with a ballpoint pen. This enables easy, smooth writing. The rollerball thus combines the advantages of the fountain pen with the easier handling of the ballpoint pen. Our rollerball pens use standard ink refills, which are available in every well-stocked stationary shop.
