UCGOU Poly Mailers 19x24 Inch Black 50 Pack Extra Large Shipping Bags Strong Thick Mailing Envelopes Self Seal Adhesive Waterproof and Tear Proof Boutique Postal for Clothing Quilt and More

My second time purchasing the Ucgou poly mailers. A great value for the price. While not the thickest poly mailers I've used, they're also far from being the thinnest and a good sturdy mid-weight. Thus far, no issues with tearing. The self-adhesive strip at the top seals well. Our customers love the color (teal) and they're a size that lends itself to many uses. All in all, a great value.

Great mailer bags and quality. My 2nd time purchasing these, but this time in black because they were on sale for a reasonable price and had prime shipping, I was disappointed the blue ones were not; didn't make sense. Thickness is pretty good, they're not see through so couldn't see what you're shipping. Adhesive seal is good, but I always go back and tape over seal for extra caution. These are easy to use, flexible, and functional. Love the size of these as well.

Fast ship, just the size I needed and quality bags!! Plus the pink is perfect. Good thickness for shipping out clothing items. Great price too!! Will be back for more.

Industrial product. Super sturdy and hard to tear. Makes packages show up to your customers looking sharp!!!

Great value for quality mailers. These are lightweight and thin but seem strong and durable. (Not nearly as thin as some others I have used). They are true to size and fit great for my needs. The self-adhesive closure is easy to use and effective. They are very flexible and easy to fold to fit in your mailbox or tape them up shorter if you need a smaller bag. Great value for the set and a great product.

I'm a Reseller on several online selling platforms. I use numerous poly mailers every single day to mail out packages. I found this brand to be of good quality and strong enough to go through the shipping process. I've purchased several different colors.

Right size, the X-large 24" x 24" big enough for shipping BIG items. The turquoise color is nice too, a friend commented that the package looked like it's from "Tiffany"! LOL.... It's kind of nice to brighten up the boring, ordinary shipping packages. We use these mailers to ship items that came with their own original boxes, this poly mailer is much lighter than shipping in another box, for this large size in weight it sure saves shipping cost quite a bit. Although, wish the material is made from degradable kind of plastic, more environmental friendly. Hate to add more plastic to the world bec of the nature of the business with shipping & packaging. Sturdiness is fine, but wouldn't really call it tough and tear resistant, because there're times when the bags though didn't tear open or rip, but would show bubble at points/corners where there's extra pressure causing stretch, so that area would seem vulnerable to tear bec of thinning in material, so we had to reinforce it with more taping on top of it as a precaution. Thanks for shipping them to us quickly, just when we needed.

These are perfect. Thick, and glue strip adhesive is strong. I had to return ones that I bought from another seller because the adhesive didn’t stick and they were paper thin. These are perfect!! I know do a fact these will make it through transit without breaking. Thank you!!

Me encantaron

These are amazing packages. Love the colour, and the easy peel off to get to the sticky part to clothes the package. It does stick so well! It is so secure. You do not need to worry about it unsticking. They are so sturdy and can handle being thrown around in the post office. Would recommend if you are shipping small-medium size items.

Es resistente y su tamaño es perfecto

Great value for the bags. I ship daily and these are a great product. Shoes and clothing fit nicely. Products arrive intact and have not had an issue of tear or bags opening.

Overall a good price for the amount but I do agree with other reviews that they are a little thin. Not too bad for smaller items since you could pretty much double lay it but I would have expected thicker.
