Nontoxic. Cleans up completely (Crayola Beginnings Washable Triangular Crayons are designed to easily wash off walls with just warm water and a sponge). Guides little fingers toward a writing grip! Crayola Beginnings products build children's creativity, independence, and confidence through hands-on exploration. Specially designed for toddlers, the art experiences they provide engage and inspire children as they create and grow. As children approach 24 months, they begin to hold crayons with the thumb and two fingers. Washable triangular crayons are the right shape to help guide their fingers into the tripod position for more purposeful and controlled drawing. Their scribbles now look like zigzags or tighter, more controlled circles. The tripod grip is important for developing later writing skills. Safety Information: Conforms to ASTM D 4236. All Crayola art materials are nontoxic. Product of USA.
