Feel the sense of history as you fill your converter with bottled ink. Practical benefits include the massive array of ink colours, which can be mixed to create any shade and hue (see Platinum mix free inks). We stock a selection from the major brands, as well as a standard converter that can be used with any fountain pen that takes international ink cartridges e.g. Otto Hut, Coles Deluxe.
