Keep It Fun, and make someone smile, with our tennis ball bouncing along to spell a very special "Thank You." The A2 size, 4 1/4" x 5 1/2", cards are printed on heavy 110 lb. cardstock. Cards are available singly, but when ordering 4 or more cards, the price is reduced to $3.50/ per card. 4 or more will also come in an attractive, handmade cardstock folder (paper designs are varied and chosen by us) with a matching belly band. All cards are wrapped in cellophane for protection. For your convenience, heavyweight envelopes are included.
