Really pleased with the card quality. The perfect theme to personalize a birthday celebration. Birthday greeting combined with a Christmas wish for my nieces Christmas Birthday. Perfect! These colours really pop on this Matte finish. The cute funny monkey expressions add humour to a birthday card surprise.

I needed a nice looking 90th Birthday card for a very dear friend. I selected the sample that would work for me, and added the name. I was so surprised on the fast delivery, and very pleased with the results. My card looked so much richer than on the web-site. Such an original, great looking 90th birthday card. I will be definitely ordering more cards in the next little while. I certainly recommend Zazzle products. Amazing designs...
