FF Bull™ supports 50 different languages such as Spanish, English, Portuguese, German and French in Latin and Other scripts. (Please note that not all languages are available for all formats.)
According to designer John Critchley, FF Bull is an authentic reproduction of old John Bull rubber stamp type sets, inked to varying degrees to produce six distinctive weights. These are fully interchangeable and can be combined or overlaid to provide even more variations. Some of the weights contain special “dirt-keys,” which can be used to customize a piece of design even further.
