Abstract
Improved upper and lower paired pen markers adapted to pass over one another with minimum spacing utilize interchangeable pen cartridges which are generally flat and rectilinear with the nib of the upper cartridge being slightly longer than that of the lower cartridge. The upper cartridge is supported from above in a holder with a front overhang lip, a sidewall positioning holding member and rear spring clips. As the bottom cartridge holder supports the bottom surface of the cartridge it also includes a sidewall positioning holding member and rear spring clips. Mispositioning of cartridge and holder is minimized despite the generally flat cartridge configuration.
