*Look exactly like advertised, but the holographic quality looks better in person than in these photos.*Appear to be very sturdy & of great quality.*Received all 25 and they were well packaged.*I did not thoroughly inspect each individual envelope, but I did not see any noticeable flaws on them. They look really cool!* I am not sure how great the seal works yet, but I personally don't mind because I always tape around the sealed edge anyways with clear tape to make it extra secure.*I included a picture with a 6oz container next to it for some perspective of size. When put inside, it looks like you could stack 2 of these jars in it even, but it probably wouldn't close well.* I do have a jar that is twice as big as the one pictured (height and diameter) and it fit inside the envelope, but you would have to use a lot of tape to get the flap to actually close.******I would definitely recommend these!!I am the owner of a small business, that operates mostly through instagram with direct sales to my website. My items range in size but are primarily fit in a 4x7 poly mailer. I was releasing an item that had multiple parts to it, and wanted a pretty bag just a tad bigger that would fit all of my items and would hold up while being processed the USPS system. These were WAY better than I could have bargained for. They are extremely high quality, and are pretty to look at! I slap a sticker of my logo on the back over the seal and everyone is always so excited to share their "magic mail" on instagram with my logo! Would highly recommend! As someone who reads reviews (way too many, I might add) before purchasing something, if you found my review helpful, id love to know down below if you could mark it helpful. Thank you!Perfect for my jewelry business! Just don’t leave them in the car when it’s hot Bc the adhesive will melt and the package will open. Other than that, these are bomb.All is good but, when I tried to place a slim 4x6 box ,again it is slim, it did not fit at all, the bubbles take up more space than I imagined. Overall cute packaging. Price is a little elevated I've seen 25 for $6.99. Might return. The sizing and price is really pushing me to return it.Wrong size stated, the opening for the mailer is really like 4 inches. And the cards I ordered for my packing was 5 x7, couldn’t even force to fit if I wantedI love the Glamour Holographic bubble mailers. I use the mailers to ship merchandise and my customer love them as well. The color is gorgeous and it adds that extra glam to showcase the merchandise. I would highly recommend this product the quality is great! I will purchase time and time again!They all LOVE a shiny present….It looks really great , makes my customers excited to open the package .Perfect size. Fancy.
