But I've shipped catalogs from U.S. to Canada via the Post Office, and one got returned back to me. The envelope still looked in good condition if that helps any. **Q: Does anyone know if the envelopes come with the seal flaps up or down? I know this is being picky, but they will not fit in my storage cabinet if up.** A: They come in a box with the flaps down. You should be able to open the box up and take them out and add them to your cabinet! Hope that helps! **Q: Can i send a 11*8.5 photo using this letter? I'm worried that the photo may bend if the envelope is not made of hard board.** A: This is a soft envelope. You could put a piece of cardboard on each size and then use this envelope. **Q: Does this bend easy?** A: These are like any other regular envelopes and would bend if mishandled. They have the kind of paper so you can't see important papers that are in the envelope. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Ideal for Small Catalogs *by J***S on September 9, 2026* Made from 28 lb. paper, these envelopes are ideal for small catelogs.
