These crayons were created to benefit the Juvenile Diabetes Research Foundation. My daughter Casey was recently diagnosed as having Type 1 Diabetes and our cousin Eric was diagnosed with Type 1 in 2000. 50 cents from the sale of each crayon will be donated to the JDRF. Great idea for birthday party favors - Specify colors wanted when placing order. Each crayon was made from used Crayola crayons donated by the students at Meiklejohn Elementary School in Arvada, CO, Chestnut Charter Elementary School in Dunwoody, Georgia and Mt. Bethel Elementary School in East Cobb, Georgia . These crayons are also non-toxic. They are approximately .5" x 1.5". Colors available are those in picture - red, yellow, blue, green, light green, pink, orange, purple, black. All items were created in my smoke-free and animal-free home.
