The U.S. Postal Service faces a bevy of dilemmas that might sink them, from the pervasiveness of email and social media to the power of Amazon. Luckily, they have an ace up their sleeve. Meet the scratch-and-sniff stamp. BOOM! Deal with that, Bezos, you fool! The new collection of stamps, dubbed “Frozen Treats,” feature illustrations of ice pops and other summertime sweets, each of which releases a scent when scratched. Each book of 20 Forever stamps includes scents like chocolate, kiwi, watermelon, root beer, blueberry, cola, and more. The unveiling goes down June 20, in Austin, Texas, but you can pre-order here soon. Sorry, email, you had a good run.
