Love these! Just what I needed. Stiff, nice size, easy to close.

great mailers!

Perfect for large prints!!!

Sturdy and adhesive sticks well

I ordered these (in kraft) because in the product questions, the manufacturer stated they were made of 28pt cardboard. I bought these to replace my other 28pt mailers in the same size (9.75x12.25) from a different manufacturer because of inconsistent products with my other manufacturer, and when these arrived, I could immediately tell they were nowhere near as stiff. I weighed these and they were only 2.7oz vs 3.5oz for my normal 28pt mailers, which is a huge difference. Judging from the product weights in the listing, the white mailers in the same size, which are considerably more expensive, are actually 28pt, but the kraft ones are considerably lighter and are not.My old mailers were very reliable and would only need one piece of cardboard stiffener when mailing prints, but these would definitely need two. The corners in my old mailer were also practically indestructible, and these corners are very flimsy.However, I do give props to Stayflats for sending all their mailers in boxes that can handle the weight and don't break apart in transport (which has happened to me every single time with every other manufacturer), and their mailers come with no funny smell (also happens a lot with other sellers). The middle seam design is also something I prefer in my flat mailers that not every seller provides consistently.If these were actually more heavy duty 28pt mailers, they would easily be a 5 star product. But I don't know if I can use these for my business without worrying about my products being damaged in the mail. I'm honestly very disappointed because I thought I had finally found the one in terms of flat mailers.

I mail a lot of photos and these mailers are perfect for photos printed on 8.5 x 11 photo paper.
