Review on 50 Pack Of #0 Royal Blue Metronic Bubble Mailers - Strong Adhesion Padded Self-Seal Packaging Bags With Cushioning Bubble Envelopes, Waterproof And Ideal For Shipping Jewelry, DVDs, Makeup, And More by Weston Metzger

I won't buy these again. I'm happy with the size and the bubble wrap padding is adequate but I don't trust the adhesive to keep the envelope closed during shipping. Whenever I receive a new pack of shipping mailers I will test one or two and these appeared to fail. My testing is simple, I just close the mailer, really press it sealed, and then try to pull it opened. The first one the adhesive part pulled cleanly off then the second the adhesive pulled from the padding part without a lot of force.I'm not an expert on mailers but to me it appears the adhesive isn't that strong. Also on most mailers the adhesive doesn't go all the way to the ends, leaving the flap open.I'm always looking for the best deal to save money on shipping costs wherever I can but with these mailers I'm using more packing tape just to make sure they won't open during shipping.I have a bunch left but I'm looking for replacements as I type this.
