Patent abstract
A two-nib crayon includes two crayon halves of different colors, each crayon half including a flat end and a nib end. The flat ends are fused together to form an integrated one-piece structure such that the respective nib ends are disposed in opposing relation. The two-nib crayon makes learning exercises using a color activity more fun.
