More than 5 billion crayons are produced each year

More than 100 billion crayons have been produced so far. The first crayons consisted of a mixture of charcoal and oil. In the early 1900s, cousins Edwin Binney and Harold Smith developed a nontoxic wax crayon. Binney's wife, Alice, attached the French word for chalk, craie, with "ola," from oily, to form the Crayola name. Their first box of Crayola crayons were sold for a nickel in 1903.

The first Crayola crayons came in a box of eight colours: black, blue, brown, green, orange, purple, red and yellow. By 1957, 40 new colours were introduced. Today there are more than 120 crayon colours, including Atomic Tangerine, Blizzard Blue, Mango Tango, Outrageous Orange, Laser Lemon, Screamin' Green and Shocking Pink. Over 5 billion crayons are produced each year.
