Abstract Santa or decapitated Santa? You decide! These cards are 5" x 5". The abstract Santa is mounted on a white 5" x 5" square card. The holes in Santa's belt are silver eyelets. I am selling them as a set of 4. This is a square card with a square envelope so an additional ounce of postage is needed because it needs to be hand sorted by the post office. 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 (least expensive card is free). The individual price of these cards is $3.50. I don't charge for shipping within the 48 continental United States. If you live outside of that area, please message me and I can give you an estimate on shipping costs. Thanks for shopping!
