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 wanted a personal Birthday card for a dear friend who was turning 84. I was very pleased with the design and the message inside the card. I'm very pleased with the results, and certainly will order Zazzle cards in the future. I certainly recommend these beautiful cards...
