These colors are $5.50 per set of 25. They are A7 size and perfect for your 5x7 photos or cards. You'll also be happy to know that they all contain 20-30% PCW (post-consumer waste - that means recycled material). They are nice and sturdy 60 lb. envelopes. Midnight and Natural are 70 lb.
These colors are $6.00 for a set. They are also A7 size and some are even 100% PCW. One of my favorites is Grocery Bag. It has the texture and weight of a grocery bag and they are just awesome envelopes. For the details by color (or to purchase), click here.
