Boosters is very excited about our new product and its potential for revolutionizing the art of expressing school spirit on automobile windows, building windows, banner material, and posters. Carchalk is a non-toxic ink that will hold up to the hardest rains but will wipe off easily with water and a wet cloth or paper towel. The wetter Carchalk is, the easier it cleans up. Carchalk is available in several colors: red, blue, orange, green, gold, purple, white, & black. Colors can be combined for quantity pricing. Carchalk is shipped within 48 hours. (Production times do not include Saturday, Sunday, or Holidays.) Please see our shipping map for estimated ship times.
