This is the poly mailer brand I always use. They’re strong, waterproof, and the adhesive seals well every time. For some reason, the black ones are better quality than the other colors from this brand, so I always stick with these. Great value and very reliable for shipping.

These 12 x 15 black poly mailers have become my absolute go-to for shipping. I’ve used a lot of different mailers over time, but these stand out for all the right reasons. They’re nice and strong — the plastic feels durable, not thin or flimsy like some others I’ve tried. I’ve never had one rip or tear, even when packing bulkier clothing or odd-shaped items. The adhesive strip seals securely, and I feel confident shipping with these knowing they’ll hold up in transit. The black color also gives my packages a clean, professional look — great for branding and a step above standard white or gray mailers. I’ve reordered these and will continue to. Highly recommend for anyone needing dependable, high-quality shipping bags.

Work perfectly. Strong and the glue is stuck for good if it touches. Won’t open. You actually have to be careful not to let it touch too soon. Great stuff!

This 2nd purchase, the adhesive tab is not as thick as the first set, a bit of a difference but not bad still like them a lot. The material is also not as shiny as the first time I purchased. A bit dull looking but still I like them a lot. I would want a different colour but the price is amazing for the plain black...........Still a BUY BUY BUY for me. I had purchased these polymailers and only a few left from the first order. They are great! They are not thick but very strong. The colors is true black and the adhesive is amazing. Out of the 100 pack not 1 was a problem. When you peel off the adhesive that's it, no turning back. Never had an issue with any holes or tearing. Great product. The second order which I have, it came packaged not so nicely but if the quality is the same there is no complaints. I will update, on the second pack. I've ready counted the second pack, yes I'm that person. I would like other colors but because I trust the quality of the black and the price was amazing. BUY BUY BUY!

I recently purchased KKBESTPACK 100 Pcs 12x15.5 Poly Mailer Envelopes Shipping Bags Self Adhesive Waterproof Bags in Black, and I have to say, I'm quite impressed with the quality of these bags. Firstly, the self-adhesive feature of these bags made the packaging process so much easier and hassle-free. The bags are also waterproof, which ensured that my products remained safe and secure throughout the shipping process. The bags are quite spacious, and I could easily fit in all of my products without any difficulty. The black color of the bags looks very professional, which adds to the overall presentation of the package. The only reason I'm giving this product 4 stars is that I found the bags to be slightly thinner than what I was expecting. However, this didn't compromise the quality of the product in any way. Overall, I would highly recommend these Envelopes Shipping Bags.
