KKBESTPACK100 Pcs 12x15.5 Poly Mailer Envelopes Shipping Bags Self Adhesive Waterproof Bags (Black), 12 x 15.5

I purchased this 100-pack of 12 x 15.5 black poly mailer bags for my small business, and they’ve been fantastic. The size is perfect for a variety of items, and the black color gives a professional, sleek look to my packages. The material is strong and tear-resistant, with a secure adhesive strip that keeps everything safe during shipping. Having so many in one pack means I won’t run out anytime soon. Definitely a great value for anyone needing reliable mailers in bulk!

Great quality poly mailers! The pack of 200 is perfect for my small business. They’re durable, lightweight, and seal securely—no worries about items getting damaged or opening in transit. The material is thick enough to provide good protection, and they look professional. Excellent value for the price!

Why did you pick this product vs others?:I chose these because they are HUGE, large quantity, and can use for anything.I use these to sell on depop/ Poshmark, sell my jewelers pieces, and to mail family gifts. It seals on itself so you can just wrap smaller items. Allows room for bubble wrapping smaller items as well! I like the sleek black look and other sellers had some crazy prints!

Good quality. Perfect for shipping clothes. Seals strong

I do clothing resell as a side hobby and needed something to ship the clothing in that wasn't a box. The bags are made really well. They feel very nice and thick so I don't fear that they will be ripped during shipping. I have been able to ship as big as a small sweatshirt, shoes and regular t-shirts. They are thick enough and dark enough that you can't see through them. These bags make shipping very easy, unlike shipping in a box, they will actually fit in the mailbox. Definitely recommend!

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.

I’ve purchased these vinyl shipping envelopes several times now. They’re waterproof so perfect for shipping. The sticky tab seals great tooWhy did you pick this product vs others?:Price and materialWorks well:Works very wellWeight:super lightweight Adhesion:excellent Functionality:works with a variety of sizes

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!
