Sten and Lex are among the most internationally renowned street artists in the world. The Italian duo has developed an unique technique, the halftone stencil, which allows them to create poetic and powerful pieces influenced by op-art. Sten and Lex first met at the end of medical studies in Rome, while taking a radiology course together. They were profoundly inspired by the material potential of x-ray film, and it was during class that they first began to cut out the skeletal forms, a process which foreshadowed their current practice.
