UCGOU Bubble Mailers 8.5x12" 25 Pack Usable Size 8.5x11" Teal Shipping Bag

I have been using these to sell my books through Vinted and they have been great! They are durable and get all of my books to customers safely and without any damage. I have already purchased them 3 times. Highly recommend for sending books or other fragile items in the mail. Great purchase!

Excellent product. Durable, eye catching colors, and protective for content. I'm a small publisher and often get orders for 2-3 books. These bubble packets are perfect for those small orders. The books always arrive in mint condition.

These UCGO Bubble Mailers are great! I highly recommend them. They are not too small and not too large. 8.5x12 can fit several small boxes in it. I sell jewelry, so this is the perfect size to fit the pieces that are in boxes, into the bag. These bags are eye catching with the beautiful shade of purple. The bags self seal securely, so no glue or tape is needed. These bags are padded and waterproof, so whatever you may be shipping out in these bags, you can feel confident that your products will make it to the receiver, in excellent condition. The price is good and you can usually find a promotion code that is offered.

Beautiful color for my book shipments! I have this in pink, envelopes are thick, protective, and great price!

These are the perfect size protective envelopes for my jewelry that I ship out

Shipped fast, great quality and price

I put cardboard backing insert inside this package together with my product. The insert size 7" x 11" fits perfectly inside. So that's the available space. Insert 7.25x11 won't fit. I think my insert is around 1/16 or 1/8 inch thickness. Besides that, the mailers look exactly like the pictures and are light weight, just as described.

Sturdy and well made, these bubble mailers are perfect for shipping 6 x 9" paperback books! And I love all the colors available!

UCGOU Bubble Mailers have become my go-to party planners for the postal world, turning every delivery into a bubbly extravaganza. It's the kind of mailer that says, "Mailing? Let's make it a bubble celebration!" The poly-padded magic is like a protective dance for my packages, ensuring they arrive in style and safety. I half-expect my parcels to start throwing confetti upon arrival. Now, why the enthusiastic 5 stars? Well, these bubble mailers come in a pack that feels more like a VIP invitation to a mailing fiesta than a simple packaging solution. While my packages are enjoying the bubbly protection, my budget is doing the frugal fandango. In conclusion, 5 stars for UCGOU's bubble party mailers. If you're ready to turn your mail into a celebration of protection and style, these padded envelopes are the postal party planners you didn't know you needed! 🎉📦🌟

Arrived when expected. Envelopes are decently padded, are the size I was looking for, and colora vibrant. Very happy with purchase and will purchase again.

good adhesive strip

Great mailers. Not the thickets bubbles, but for the price, this is exactly as I need. Love the bright pink. the adhesion is so strong - don't mis-stick by accident! I do have to tape the edges though because the adhesion strip doesn't go to the end, and while i feel my package would be safe and not open, I prefer to be certain.

I got other ones and the bubbles were super flat and didn’t feel secure. These ones are the best I have found so far
