This 2024 Calendar card features a tear-off mini calendar and displays via an easel mechanism. This is a single card that measures 4.25" X 5.5". It will fit inside the included envelope for mailing as a gift. The inside has a raised design to allow the front to tuck behind it for display on flat surfaces. There is not much room for any additional messages inside the card but a separate note could be added. It will mail in the US for a single Forever stamp.
