Happy mail is one of the best ways to cheer someone up! Its a proven fact! There is no way that receiving this 3D Cake Post Card wouldn’t bring a smile to your friends face! It is literally a slice of cake that you can put directly in the mail, can it get much cooler? I think not. Made out of a sponge and caulk for the icing, it looks delish! Although it wouldn’t taste all too good. I know I would love to open my mailbox on my birthday and see this adorable piece of cake inside!
