Filling a fountain pen with bottled ink reminds us of the good old days, when the pace of life was slower. Whilst filling the converter can feel onerous, a bottle of ink goes much further than an ink cartridge. A good quality ink should offer richness of colour, permanence, smooth flow, no clogging, no unwanted deposits and fast drying. Read our ink colour comparison. Sheaffer offers a good quality ink with good saturation, whilst Platinum's mix free inks can be combined with each other for unlimited shades.
