100-11x13.5 RIGID PHOTO MAILERS ENVELOPES FLATS BY VALUEMAILERS

I have purchased these mailers several times and am always happy with them. Many times my customers have mentioned how well their product was packaged.

I use these for shipping 9 "x 12" music books singly or multiples up to a couple of inches thick. Need a rigid mailer to prevent damage / folding in transit and thick enough to be water resistant during delivery.A bit pricier than I would prefer, but cheaper than many alternatives without buying massive quantities.Self seal works great, I just tape the edges if the package is on the thicker side to seal any gaps. The finish is great for adhering mailing labels and logo etc - i've had problems with some of the 'brown' ones being so 'fluffy' that labels don't adhere well and could peel off in transit resulting in lost mail.

These hardboard flat mailers are rigid. I had no worry of it bending through the mail. Excellent value.

The media could not be loaded.  These are a great value and quality. Everyone I've sent things to in these said they arrived in perfect condition and not the slightest bit bend. They are all white and look nice and clean for mailings. I will order again. Check out my video and pics for more details/comments.

Great product, sturdy and glues instantly

Awesome quality- great value. I use these to ship paper doll books I sell and have never had damage reported.

I've ordered several hundred of these rigid mailers and I'm very pleased with the quality, the price and the adhesion on the closing flap. I will be ordering more.

I've been using these to mail comic books. I insert the comic sideways and fold the mailer basically in half, which increases the rigidity substantially, ideal for collected books. Nice white surface which holds sharpie ink well for neatly hand addressing or applying shipping label. Delighted.
