UCGOU Poly Mailers 6x9 Inch Navy Blue 200 Pack Mini #1 Shipping Bags Strong Mailing Envelopes Thick Self Seal Adhesive Waterproof and Tear Proof Boutique Postal Small Business for Jewelry and More

I love these mailers! I sell items on Etsy, which means I ship frequently. These mailers are the perfect size! They are made of a thicker plastic, which holds up very well. I also love that they have a built in adhesive strip. Very convenient and saves money on using packing tape. Will definitely purchase these again!

These bags are so fab. I am currently sending out home-sewn items including masks and scrub caps and all items fit perfectly. Adult masks measuring 7.5 inches in length fit flat; caps are folded in quarters and fit great. Thank you!

I own a shop on Etsy selling cloth face masks. It has been extremely busy with the pandemic and it was just too expensive to continue buying envelopes at Walmart to ship as many as 100 masks a week. These have easily fit 10 face masks with no problem. There made of a very tough thick material that’s 100 times better than my packages from the Wish app come in. The sticky for closing the mailer is stupid strong, I’m half way through the package and zero complaints about tears or coming open. These are tough and lightweight to keep yourself shipping weights down. 10/10 recommended for someone wanting shipping options that are durable and lightweight! I also LOVE the colors which stand out to my customers!

I read other reviews and I was expecting a flimsier product. However, it’s actually pretty hard to poke a hole through these without some effort.I didn’t mind the negative reviews because I ship lightweight cosmetics and I don’t need heavy duty bags. Like, what do these complainers expect from such an inexpensive bag? They need to get a reality check and realize that this is s great product for the price. I’m extremely happy with my bags and my customers love the pretty color.

Worked out great shipped fast, thanks

Needed smaller poly mailers for our business and after trying out a few others at this price point on Amazon, these are the ones you want! Others we ordered felt super cheap, were thin, and I wasn't sure they could handle the abuse of going through the post office's system. These are a great quality, thicker like our other poly mailers, and adhere well. We ship soft items so there's no issue with things poking through, but I sealed one and tore it open to test and it's a great thickness, taking some effort to open. We've now bought 1200 of these and will continue to purchase. Great product!

I use this in my tee shirt business and they work great. They are durable and the adhesive strip is good. They fit up to two shirts perfectly.

I run a teeny tiny jewelry business- finding great packaging supplies at an affordable price isn't always easy. After much searching and using subpar supplies I found these bags- I am so darn happy with them! As you can see, the color is a perfect match for my logo, yay!I was using white envelopes, but after a few lost packages I knew I needed a brighter color so maybe my packages wouldn't get lost in the bottom of the big USPS white canvas bins our mail all gets dumped into. So far, the seems to have helped- no lost packages since I switched. I'll take this as a good omen! #SaveTheUSPS

They were more of an actual teal colour than shown. The ad lists a blue toned teal. Glad they were more a green-blue. They were the perfect colour for what i wanted and fit what i needed them for.

Love them, good thickness and adhesive is very sticky

Bon produit, répond à nos attentes

Awesome - the perfect color and the right size. Will work amazing for my home based shop

Nice quality, nothing to complain about.
