Playing up the simple joy of snail mail, these irresistibly charming cards illustrated by Lucy Mail (@lucy_mail) make every note a treat to open. Each envelope in the set features colorful goodies, sweets, and comfort foods painted over the flap, but opening it reveals the real cherry on top-a little icon on the corresponding flat card that perfectly pairs with the envelope art. The assortment of designs covers every card-sending sentiment from birthday cheers and congratulations to romance and just saying hello.
