Such a cute card and well done. Sturdy cardstock and beautiful colors. Ordered a box full of cards and they didn't come folded. Otherwise very pleased with the overall product. The printing is beautiful! Looks great

Our daughter has enjoyed her Dad's jokes during her lifetime. She will get a "kick" out of this card. Everything about this card is great for the person who will receive it!!
