Review: Sturdy Poly Mailer Bags - 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.
Review: Great choice! - I am a repeat customer for these poly bags because they are very strong and the perfect size to ship many of my eBay sales. I love the beautiful, cheerful color!

### ⭐⭐⭐⭐⭐ Great bags...
*by W***N on October 30, 2025*

I have purchased these bags many times from this seller and will continue to do so. I've not had a single issue with these bags (other than user errors), and I've mailed thousands of products to customer. The tape strip is strong, and once it adheres it will not let go lol. The thickness is as advertised. They are a great value.
