Whoever invented this product must have a lot of time on their hands.

To-do Tattoos are washable tats you put right on your hand so you’ll never forget anything ever again. Use them to remember your kid’s names or reasons why you married your husband. One word of caution, don’t put personal things on your list and then wipe your brow unless you want the whole world to read your forehead to learn you need to buy tampons. The kit includes 12 graphic “To Do” forms that you can apply to your hand—or if you’re pregnant, to your belly, to remind yourself which foods make you sick.
