Large Size Adult Christmas Cards - Red Set of 2 Simple and stylish. The red color is very lovely. The cards are not folded. The back is blank. Envelope size: Approximately 13.5cm x 18.5cm How about adding these adult Christmas cards to your presents? They will be shipped with a cardboard backing to prevent bending and protected from water damage. I also have many other Christmas cards and Christmas goods for sale. If items can be combined, I will discount the shipping cost, so please let me know in advance. Thank you.
