Abstract: An eraser is placed on or near the end of the cover of a felt tip pen. The cover is inserted into the bottom of the pen or on the bottom of the pen itself. For a tapered cover type of pen, the eraser is placed on the flat upper end. For a raised or dimple type of cover, the eraser is placed concentrically around the end away from the dimple like a girdle or belt or flat on the bottom of the pen body. On a type of pen that resembles a fountain pen, the eraser is placed on the top cover on a flat area that may be slightly angled. The eraser can also be an annular ring on the base of the pen body. The eraser can be removable from the pen or can be attached with adhesive.

Abstract: A ballpoint pen with cap has an overall length which is substantially equal to a conventional credit card enabling the pen to fit snugly in a credit card receiving pocket of a pocket book. The pen has a thin, flat body containing a writing cartridge and having opposite side edges diverging rearward in plan from a front writing end to provide a broad, flat, blade-like, hand engaging rear portion. The body also tapers in thickness as it extends outward to opposite side and rear edges forming a narrow, peripheral insertion edge. The rear end is straight and the cap is rectangular so that, when assembled, opposite ends of the pen have straight edges extending substantially perpendicularly to a longitudinal axis of the body. The body has a lateral supporting and guiding lobe for engagement with a writer's hand in different positions to facilitate a fluid writing action with different pen grips.
