If your envelope doesn't get opened, it doesn't matter what was inside. That’s why it might be smart to upgrade to a larger envelope. Picture the way an over-sized envelope will look next to all the other regular mail. On top of that, the pop of green from these Green Large Envelopes will come as a refreshing surprise. Paper Booklet Envelopes, which come in a choice of different green shades, are big enough to hold large documents and promotions. Rather than folding your impressive material, keep it flat and neat.
