A humanistic sans serif in eight weights, Magma has true italics and many special features which make it useful in a large range of applications for both text and display.

Stone Type Foundry introduces for the first time with the Magma family a set of Halo fonts. These Halo fonts have several different uses including an easy method to compensate for the weight lost in reverse printing. Magma also contains several alternate characters as well as both old style and lining figures. The primary weight of Magma has a corresponding Halo font.
