An explosive idea - a bomb sharpener by Joel Escalona from Mexico City.
A humorous concept, between holding a cartoon bomb in your hand and making your homework kind of fun, specially for kids, between 5 and 15 eleven years old; the bomb has enough room to hold all the waste left for the pencil and it can be made of soft plastic, transparent plastic, and in any color. It's just the same measurements as a normal sharpener, easy to produce, low set up cost, and can do volumes.
