But they work just fine! ### ⭐⭐⭐⭐⭐ great quality *by K***R on October 29, 2025* We ship out approx. 30 orders a day that we use these bags for and we have never had a complaint yet from a customer saying that the package was opened because the adhesive wasn't sticky enough. We have gone through a couple thousand of these bags. ### ⭐⭐⭐⭐⭐ You get what you pay for *by A***R on May 18, 2023* These are thin and cheap feeling compared to other mailers I’ve used. However, I have shipped out several of these with clothing, and haven’t had a single complaint. They are lightweight and don’t add much to shipping costs. They aren’t as nice as others, but if you’re looking to keep your overhead low, this is a good option. ## Frequently Bought Together - Reli.
