Sturdy charcoal pencils with a thick white lead that provides extra sensory feedback and resistance. Pair these with our new black notebook paper and presto, it's like writing on a chalkboard! These neat white charcoal pencils are ideal for handwriting practice and provide phenomenal reverse contrast when used on black notebook paper (as the combination of the white lead on the black paper reduces the light that bounces off traditional white notebook paper). However, please note the print of these cool pencils can smear just like chalk. Another favorite occupational therapy writing tool for your "therapy bag of tricks" from the Therapy Shoppe!
