-- CraftyCroc™ Product Reviewbr 5 Star Rating from our customerbr br Fun AND practical!br br I have found many fun and practical uses for chalk markers.. I'm wondering how I have lived without them for so long! I've used them to write notes for the family on the fridge, reminder notes on the bathroom mirror to my husband, writing clean on the front of the dishwasher before I leave the house so someone knows to unload it, and my kids have had fun drawing on our windows. I have not found the stain or damage and surface I have used them on and they come in fun colors.
