Vintage Waltham Molded School Chalk by The American Crayon Company, originally a full gross of Grade B white chalk but has less now not by much. This non-toxic, molded chalk is a classic schoolroom staple, produced in Sandusky, Ohio. The original cardboard box displays iconic mid-century branding and typography, making it a great piece for collectors of vintage office and school supplies or for practical use on chalkboards. Each stick is tapered for a comfortable grip and smooth application. Made in the U.S.A., this set offers a nostalgic look at classroom history. Has a few broken pieces.
