"I love how I was able to personalize this card to include information on our wedding gift registry. The black was not as deep or rich as i expected but the matte was interesting."
"This invitation and enclosures are perfect for a bride who wants something simple and to the point. I bought them to use for my casual/fun wedding reception at an aquarium. I also bought separate pocket part layered cardstock to go behind the invitation and dress it up a bit. The pocket part allowed the enclosure cards to be neatly tucked behind the main attraction - the invitation. Otherwise, you may likely have a jumbled mess in the envelope. Overall, I would give this invitation a 5 out of 5 if you want something simple and fun."
