"I'm about to mail these invitations and can't wait for everybody to receive them! Just like the rest of the construction pals products, they're cute, fun and simple...just what you need for a first b-day party. I think they fixed the envelopes after receiving complaints about the invitations not fitting because ours fit perfectly in the envelopes. The only thing I could say could be improved upon actually does have to do w/ the envelopes...they are very thin and pretty see-through...I just didn't like the fact that you could see my phone number and email address in combination with our last name and address (if you wanted to). Easy fix on my part though...just added a little slip of paper to each envelope to cover up invitation info. Other than that, I'm very happy with my purchase."
