Here’s the black chalk you can use with the patented Handwriting Tree reverse chalkboards. Each set contains 10 sticks of chalk that give great feedback from the hand to the brain while learning letter formation. Using dark-colored chalk on Handwriting Tree’s exclusive reverse color chalkboard is especially useful for students with Autistic Spectrum Disorder (ASD), who may have challenges in transitioning from writing with white chalk on a dark-colored chalkboard to pencil on white paper.
