There's always at least one kid in each kindergarten class that eats paste, mud and just about anything they can get their hands on. For those kids, there are edible crayons.
Featured on the Luxirare blog, these crayons are made with a wide variety of ingredients, but each of the crayon's contents is decided upon by its color. For example, the brown crayon contained almonds, black sesami, wild sesame, etc. Even dried veggies and fruits were used to create some of the crayons.
While these edible crayons are mostly healthy, there are some Fruity Pebbles in the mix just to add some extra sweetness to them.
