"The makers of this ingenious coffee mug [~$8] decided to glaze it with a chalk board surface allowing for easy-wipe messaging. It comes with its own stick of chalk, so no need to ask your little niece to rip one off from school. Great for morning love notes to your sweetie or for leaving that dreaded message to your boss."
