I have to share this new Wit & Whistle product because I love it. This card is for sending your own personal secret message. (Or if you prefer it also works with risque stick figure drawings.)
Using a pencil lightly write your message in the red textured area. When you mail the note to your accomplice don’t forget to include the decoder—without it your message will be completely illegible. (Dun Dun DUN.) Available for purchase here.
