This is one happy pup! Not only is the tree decorated with tennis balls, but there's a special gift waiting for him under the tree as well. The A4 size, 4 1/4" x 5 1/2", cards are printed on heavy 110 lb. cardstock. The card inside is printed with "Merry Christmas & Happy New Year," but still has ample room for you to write a personal message, if you wish. Cards come in packs of 4, presented in an attractive, handmade cardstock folder (paper designs are varied and chosen by us) and wrapped in cellophane for protection. For your convenience, heavyweight envelopes are included.
