This listing is for a single card. Our cards are A-2 size, 5-1/2" wide x 4-1/4" tall, printed on felted white paper (100% Post Consumer Waste) with a texture close to that of watercolor paper. It's heavy too — 80#! Each card has a contrasting, square-flap envelope. Card and envelope are sealed inside a clear, protective sleeve. Let us know if you prefer not to receive the sleeve.
