I have found the envelopes referenced above to be very nice. They are a nice bright white sturdy durable and nice to either write an address on or use a sticky label on. The gum on the envelope is just right so that the envelope stays closed shut tightly. I have not had any complaints of the envelope becoming ripped in the mail and I highly recommend them. Even though I generally do not use these envelopes for catalogs I would certainly consider it if the need arose. I am very impressed with the envelope.
