Abstract: An improved writing instrument preferably made of a clear sheet plastic material and consisting of two principal parts, namely an outer border portion which is preferably about the size of a credit card and an inner pen portion that holds an ink cartridge with a pen point projecting from the end of the pen portion. For storage and carrying, the two parts lie in the same plane, forming a card-like shape. For writing, the pen portion pivots to a comfortable angle on axle pins inserted in the card portion. The user holds the outer card portion and/or the angled pen portion while writing. Both portions are preferably of the same thickness which may be about 1/8 inch to 1/4 inch, the pen portion being approximately 3/4 to 1 inch wide and about 1 to 3 inches long, depending upon the overall size of the writing instrument.
