Radium Clipper
The box states that the clipper is "A Product of the 'Radium' Cutlers." It also carries the name Otto Roth Inc. of Newark, New Jersey.
The Radium Razor Blade in the ORAU collection were another product of Otto Roth Inc. Just as the Radium Razor Blade was said to be a "better blade," the Radium Clipper was described as "the better clipper."
