Sick of Post-Its? Well, the makers of this ingenious coffee mug decided to glaze it with a chalk board surface allowing for easy-wipe messaging.

The mugs are available with four colour tops - which vary amongst yellow, blue, red or green. They also come with 3 sticks of chalk, so no need to ask your little niece to rip some off from school while the teacher's back is turned.

Great for morning love notes to your sweetie, reminding your assistant how you take your morning coffee or for leaving that dreaded message to your boss... "I need a raise!"
