This card uses one of the retired heart shaped Treat cups. The circle Treat Cups (116802) are still available in the SU catalog. I actually put a foil wrapped heart candy inside this one after I took the picture. This is a 3x3 card and when you pull the tab, the back of the the treat cup is open, and you can see the message on the inside of the card.
Hope you have a great day and thanks for stopping by for a visit!
