These cards are 5" x 6". I am selling them as a set of 4--2 birthday cards, 1 thank you card and 1 blank on the inside. The baseball in the center of the card and the red and blue paper is attached to the card with mounting tape so it pops up off of the card. I have to sell cards as a set because this site has a $10 minimum. However, you can buy any combination of cards you see in my shop. Just send me an e-mail at firstname.lastname@example.org. I can add a custom item to my shop for you as long as it meets the $10 minimum. I also have an offer--buy 4 cards, get the 5th free (lowest priced card is free). The individual price of these cards is $3. Shipping: UNLESS you request otherwise, I ship everything by First Class mail with a tracking number. Upon your request, I can ship by Priority US Mail for $6.00. (Please see my shop policies.) If your shipping address is in Alaska or Hawaii or outside of the U.S., please message me before you purchase so that I can calculate shipping costs. Thanks for shopping!
