Review on Enhanced Protection: Center Crystal Polypropylene Storage Packaging & Shipping Supplies by Robert Correa

I used them to package 13 x 19 photo prints with 13 x 19 x 1/8" foam core. The printed material and foam core went in fine, but there was no tolerance on the edges so a foam pad thicker than 1/8 inch would not fit. I would have liked some wiggle room if I wanted to use a slightly thicker foam core, but overall it looks like they do their job pretty well as long as I stick with the 1/8" foam core. Note... mine came with it Tape on the body of the bag, not on the flap.
