Crystalline by Arthur Reinders Folmer is a free faceted outline display font built from a web of sharp, irregular polygons. Its letters resemble rough crystal forms, with open interiors and broken-looking edges that keep the construction lively.
Brands centered on minerals, climbing, or experimental craft could use it for packaging and merchandise. It also suits science-fiction posters and game graphics. Across these settings, the fractured geometry turns each letter into an illustrated object rather than neutral type.
