Abstract:
A multicolor writing and painting instrument may include a plurality of hard, wear-resistant nibs at an end of the tubular housing. Each nib may have a tip. The nibs may be bundled together such that the tips of the nibs lie in substantially the same plane and approximately on the circumference of a common circle. The instrument may include an ink reservoir for each of the nibs within the tubular housing. Each ink reservoir may be configured to hold a colored ink. The instrument may include a single, hard, wear-resistant nib at an end of the tubular housing. The nib may have a writing surface. A plurality of tubes may each lead to the writing surface of the nib. The tubes may form a plurality of openings on the writing surface. The openings may be arranged in clusters of one or more openings. Each cluster of openings may lie approximately along a circumference of a common circle. There may be a separate ink reservoir within the tubular housing for each cluster of openings.
