The most beautiful envelopes! They came on time and were high quality (I paid slightly extra for the linen texture).

I purchased these to send out my wedding invites in. We were trying to stay simple and I didn’t want to spend a ton of money on the invites. I started looking into envelope options because were we ordered our invited did not have envelopes as well that already had the return address printed on them. I stumbled across these and immediately knew it was the answer I was looking for. My fiancé and I have received so many complements on the envelops! It has been such a good touch to make our wedding even more personal. .
