Perfect for clothing and they are thick. I’ve used a lot of different brands and these by far are the best quality ones I’ve used. They are way thicker and just have a very nice feel and look great with the thank you.

I’ve been happy with these mailers, as I sell online. They’re an upgrade from my previous poly mailers. Quality is good, and I like the ‘thank you’ on the packaging.

Purchased these to mail out some re-sale items, and I was pleasantly surprised with the quality and thickness of the bags. They are very thick and will do a great job of protecting mailed items. They are a great value for the cost, and the design is pretty as well. Would definitely purchase again.

Good-quality poly mailers—you can really feel the difference in quality. They are durable, well-made, and perfect for shipping. The self-seal works great, and the material feels strong and waterproof.

I have a small ebay store and needed bags to ship out my items. I let my friend use a few and she was impressed by the quailty. Nice to look at and very well made. Will buy again.

These are significantly thicker than other mailers I have used in the past -- very happy and impressed about. Only negative I have with these are slightly smaller than the other 10x13 mailers I have left. I did measure them, and they are right on at 10 x 13. Have not used them yet to ship an order.
