This 16-card birthday assortment comes in a decorated box with a Velcro closure.  The cards themselves are square, but they come with a rectangular white envelope that is specially designed to fit the card so it does not require extra postage.  Because this is a packaged product, it does not qualify for free shipping like the individual greeting cards do.  However, if you also have some individual cards in your cart, those individual cards will ship free.    


Product Details:  16 square 5 x 5 birthday cards.  4 each of 4 designs with 16 full-size white envelopes which do not require extra postage.  Decorative box with velcro closure.
