Keep It Fun with our tennis ball bouncing along to spell a very special "Merry Christmas" greeting. The A4 size, 4 1/4" x 5 1/2", cards are printed on heavy 110 lb. cardstock. The card inside is printed with "and Happy New Year," and 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.
