You can get "red" and "blue" crayons with any old set, but with the 64 pack of Crayola crayons you get to spice up your pictures with exotic colors like "Robin's Egg Blue" or "Purple Mountain Majesty"! The 64 pack continues its tradition of being the ultimate pack of crayons with features like the built-in sharpener in the back of the package, and two-level "theater-style seating" for the crayons which makes them easier to grasp! Crayons measure 3 5/8" x 5/16".
