Or you can’t see anything inside** A: No, but is not a sturdy poly bubble mailer, very flimsy material. No, you can’t see anything inside. It’s okay if you just want something you can mail. but I my image (Packaging) is important to me so I would not purchase them again. Hope that helps. **Q: What is the weight per mailer?** A: slightly less than an ounce **Q: What is the Inside dimensions of the 6x10? Planning to use it for flat products** A: The inside will hold a piece of 8 1/2 by 11 piece of paper folded in half .. it is about A half inch on each side perforated **Q: How many stamps would I need to to mail this?** A: Depends on the weight. It's an oversized piece of mail so it has a surcharge over regular first class postage. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Handsome *by L***Z on January 18, 2026* These are Perfect for Manly-Man items and Women Love them too-They have a nice sleek look when you add a Thank you sticker near the address label-I've received Positive Comments from my Customers-LOVE THEM!!!
