Abstract

Magnetic pencil has a lead contg. a compsn. which can be attracted by a magnet and which may be metal, alloy or ceramic; of particle size 1-1000 mu, bonded with a non-soiling binder, opt. mixed with a pigment, Messages written with the pencil can be suspended vertically on a wall by a magnet without the use of adhesive tape or drawing pins.
