Review on Coral Bubble Mailers: Waterproof Padded Envelopes For Shipping And Packaging, Pack Of 50 #000 Size by Azeem Mendez

I just got them and noticed right away they seem small. I had been using 6 x 9 inch mailers but I typically dont need packages that big- the length is mostly what I cared about- so I figured the 4 x 8 should've worked but it was too small. I measured it. not sure how you're supposed to measure these things because if I include the folding flap (which doesnt make sense to me so I didnt in my photo) but for argument sake, if you include it in the measurement, it is over 8". so that must not be how they measure it. ok so, then I measured right to where any normal person would fold the flap over and that it only 7".As shown in my photo you could arguably fold it at 7.5" inches but unless shipping something relatively flat, I'm afraid it wouldnt hold up during shipping and would need to tape it to be sure.So basically these mailers are truly more of 4 x 7 in size. They will work for some of my smaller items but not for the items I intended on shipping in these. I havent sent anything with them just yet so I cannot review based on performance but felt like the size difference was worth noting for other customers.Ps. I measured my store bought 6 x 9 mailers. they measure 6 x 9 properly.
