Take Anywhere Blackboard Chalk Mat
What do you give your boys to keep them entertained while in the waiting room or while you are enjoying a much needed coffee break? If you don’t want to go with the pocket computer game option and want to go with a more creative, less expensive option then the Seedling My Blackboard Chalk Mat is sure to keep your boys quiet and occupied during the times when you need them to be. Simply unroll the mat and let them get busy drawing with chalk (eraser included).
