This is a set of stacking pencil and crayon. Each of the two have 10 pieces. Each piece is a colorful ball with a smiley face on it. These smiley face balls can be stacked on top of each other forming the pencil or crayon respectively. A cover is provided for covering the bottom most writing tip. The bottom most tip can be used for writing or drawing, but if the tip becomes blunt or unsuitable for writing, the bottom most ball can simply be removed and stacked on top of the chain. Simple to use, this smiley ball pencil and crayon set is great for writing, sketching or coloring.
