Music
Music Pen Cap is a set of pen caps for the watercolor pens used by children aged seven to twelve. Each cap gives a different tone, so the twelve caps together form a simple musical scale. The sounding points vary in thickness, and the surface is colored and finished with a coat of varnish. A raised tip allows the cap to be pushed on or off with the thumb. The design aims to reduce the loss of pen covers and to keep interest in painting alive. Small numbers can be printed in photosensitive resin, while larger runs can be molded in polypropylene or ABS plastic.
