Rigid Mailers 30 Pack 6.25 x 8.25 inches Brown Self Seal Stay Flat Bulk Cardboard Kraft No Bend Mailers Peel and Seal for Document Photos Pictures Papers Files CD

Great quality. I use these a lot for my art. I will continue to buy and use these. Very stiff and look great!

These are Fabulous!! Perfect thickness, durability, and amazingly light weight. The self seal adhesive is easy to maneuver. Love this mailer!

Ordered the 9.25 x 11.75 inch size to fit 8-1/2 x 11 inch papers and heavy certificates that I wanted to send via USPS Priority Mail 9-1/2 x 12-1/2 inch (flimsy flat) envelopes. Just the right stiffness so I know contents won't be bent on arrival. Purchased multiple times and have been happy with consistent quality :). Highly recommended!

I bought these as I own an online sticker shop. Most of my stickers get sent out in paper envelopes but I currently have a seasonal item that is bulky but would not be cost effective to send as a parcel. So I bought these to send them as a non machinable letter. They are incredibly stiff and good quality. I also tested the adhesive on one and could not get it open. Which is great.I might start sending all my larger orders out in these instead of bubble mailers. I’m not sure yet I’m waiting to make sure I don’t have any issues with the ones I sent out as it’s my first time using them. But it’s a lot cheaper using these than a bubble mailer. It only cost me 1.47 to send one of these at 2 ounces vs a bubble mailer is almost $4. The only difference is the bubble mailers come with package tracking.

Really nice quality envelopes. I use for mailing artwork and they were exactly what I needed. Good adhesive.

I used these to mail out calendars and other personal documents. I was impressed with the quality of the envelop and the privacy of the information inside once sealed. As I mail more things, I will continue to use these. Plus, you can`t beat the price!

Definitely would not call these "rigid". They are kind of flimsy and feel like they could bend fairly easily. Depending on your use these could be fine, such as for mailing certificates or other non-critical items or photos. I'm using them to mail vintage photos and find them way too thin to feel my items will be secure. When I used them I had to put an additional piece of cardboard inside to make them truely rigid which is just more work and increases the shipping weight. I've used others and will look to find them again that are thicker, truely rigid and don't require any further re-inforcement. Also would be helpful if it came already stamped or with stickers that said "Do Not Bend". I like that they open on the wide end, it makes for easy loading, and they seal securely. Not bad for the price and as I said they may be fine dependening on your use but if you're shipping anything valuable you're probable going to want something sturdier.

I use these envelopes for my Etsy business, and they meet all my needs. They provide a sense of quality and comply with Canada Post standards for letter mail using regular stamps. This is a fantastic product!

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.
