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 +E,fra 1/8+EE inch to +E,fra 1/4+EE inch, the pen portion being approximately +E,fra 3/4+EE to 1 inch wide and about 1 to 3 inches long, depending upon the overall size of the writing instrument. The card portion is connected to the pen portion by two co-axial axles or pins about +E,fra 1/16+EE of an inch in diameter and about +E,fra 3/4+EE of an inch in length, inserted into holes in the inner sides of the card portion and in opposite sides of the pen portion so that the pen portion can pivot or rotate on the axles or pins. A compressed spring is mounted around one of the pins and is inset for part of its length in a notch cut in the card portion. On the opposite side, there is a slanted notch or slot in the card portion, the other pin running through the center of the slot. The pins are preferably placed about an inch away from the writing point of the pen piece.
