Rigid Mailers 30 Pack 9.5 x 12.5 inches White Self Seal Stay Flat Bulk Cardboard Kraft No Bend Mailers Peel and Seal for Document Photos Pictures Papers Files CD

Bottom line is very sturdy and rigid, very strong adhesion even when packed full BUT low weight for shipping cost. Measurements are slightly larger than 8x6, however this does not affect the cost when mailing through USPS Ground Advantage. Ground Advantage is more price sensitive to distance and weight. So, I have mailed one 4x6 photo and 1 page letter and the price has been as low as $3.90 which was the cost for 1 oz. I have also mailed 7 oz and cost was only $4.90. The weight of one of these rigid envelopes is .93 oz. So, very sturdy but light. A+

I use them to fulfill photo orders. Perfect for 8x10’s. I’ve had no complaints of bent photos.

These are perfect for shipping vinyl decals without being too expensive. Sturdiness was a pleasant surprise.

Same ones used by UPS/FedEx except no words to cover up. Sturdy, adhesive stays down.

These are my go to cardboard rigid mailers from now on. I have ordered from other manufacturers in the past, but the sizes were never quite right, and the cardboard was very thin and bendable. The quality in these cardboard mailers is excellent. Nice and thick, not bendable, a nice size. I use these to mail 6 x 6 handmade cards and many of the other envelopes that claimed to be 6 1/4 wide are not even 6 inches wide inside. These are perfect. The 7 1/2 x 9 1/2 size is exactly right for what I need, and I highly recommend these rigid cardboard mailers!

This is a great value for the price

The envelopes are the perfect size for my business, which involves mailing children’s coloring/activity books. Plain white with no other markings (ie “to” and “from”), so I don’t have to worry about covering that up with my shipping labels.

I use these to send BD cards inside them, if I'm including a check or a gift card.......it's safer! Mail theft DOES happen and I think greeting cards are a target for thieves......they're more likely to steal something if they think it's holding something of value.

Très belle qualité. Envoie rapide

These are nice envelopes but a tiny bit flimsy. I think they will work for my needs but I have other ones that are more rigid. Ordered these ones as I need them for the slightly larger size over my other ones. Just wish they were as rigid. Overall they are not too bad but keep in mind they are able to bend somewhat.

Overall quality is great but I was expecting a pack of 30, only had 25 in the package. Adhesion is good but not a full seal.

I was very disappointed in these envelopes. It looks like they are made of flimsy bristol board or card stork, not cardboard like more expensive options. As soon as I recieved them, I could tell they would not work for my use to mail photos and immediately returned.
