Creating a first prototype is often challenging, but Cassidy Goldstein did it by accident. At age 11. While trying to use crayons that were broken, making the pieces too small to hold, she searched her arts and crafts supplies and found a small plastic tube meant to keep flowers fresh during shipping. She inserted a crayon piece into the tube, and drawing became easy. She filed an application and received a utility patent for Crayon Holders in 2002. Her father, Norman Goldstein, helped her get a licensing deal in which she receives a 5 percent royalty on all sales. He also founded By Kids For Kids to help youths in the invention and commercialization process.
