Chalk-O-Rama crayons

Chalk-O-Rama Dustless Chalk Crayons give you the freedom to write on almost any surface (paper, glass, wood, whiteboards, and yes, chalkboards) with no dust to clean up. Leave yourself a love note on the bathroom mirror or write your constituent feedback on Susan Collins' sidewalk (bail not included). 

Encased in plastic barrels with twist up action, these 12 vibrant colors are permanent on porous surfaces like fabric so small children might need supervision with these.
