This 3″ metal button can be tacked onto your shirt, coat or backpack, and lets you share your doodles and thoughts with the world. Comes with chalk, eraser and magnets for hanging it on your fridge.
Attach the Chalktrail to the rear wheel of any bike, and kids (or grown-ups) can draw fun geometric sidewalk graffiti as they ride. Each chalk stick draws a 1.5 mile line. Scooter version coming soon.
