Abstract
Abstract A holder for a lens-marking pen attachable to the pen oppositely of its working end and having a rest in the form of a spring arm adapted to extend along a side of the pen to a bifurcated termination straddling the pen's marking tip and resiliently biasing the tip away therefrom. In its function as a pen rest, the bifurcation of the spring is placed against a lens or other surface to be marked for steadying the pen which may then be depressed to bring its marking tip into contact with the surface between legs of the bifurcation.
