It is difficult for every child to afford classroom supplies sometimes. Having a set of crayons on hand for your class can make it easier for your students to have the supplies they need. The Crayola® Jumbo Classpack Crayons, 25 each of 8 colors 200/set, has enough crayons for everyone to share. What Is the Diameter of the Crayola Jumbo Classpack Crayons? The big box of Crayola crayons contains the larger diameter crayons. The Crayola large crayons Classpack measure 5 inches in length with a diameter of 9/16 inches. This wider width allows smaller hands to grasp the colors with ease and helps them learn the fine motor skills necessary later in life. As they are made of wax, you should store them in a relatively cool environment. At 105°F, the crayon begins to soften. At 128°F, the wax melts. What Are the Colors Available in the Crayola Jumbo Classpack Crayons? In the Crayola Classpack, you get the eight standard colors. The list includes black, red, yellow, green, blue, purple, brown and orange. There are over two dozen of each color so everyone in your class can have a set of their own without having to share. The crayons come in a sturdy cardboard storage case with eight compartments so you can organize them by color. It is an excellent way for your kids to have access to their crayons and be able to put them back where they belong at the end of art time. What Is the Suitable Age Range For These Crayons? The Crayola Crayons Classpack is for ages four and up. However, as these are the large diameter crayons, they are best suited for the lower end of that age range. Children as young as 1 to 3 years old may also color with these crayons if they are carefully supervised. The wider diameter does not prevent them from being a choking hazard. Crayola uses non-toxic wax and coloring in their products, so you do not have to fear accidental ingestion.
