Wind the wings and tuck the butterfly into a card (or a book!). When the recipient opens the missive, the lovely butterfly takes flight for a joyous surprise! (You might want to issue a gentle warning to anyone who is easily startled.) Perfect the birthdays, weddings, and other special occasions, these ingenious little creatures - which can be used over and over again - deliver soaring declarations of love and good cheer. See video below for butterfly in action.
