Black Bubble Mailers 4x8 Inches 50 Pack, Usable Size 4X7" Bubble Envelopes for Small Business, Padded Envelope, Shipping Mailers, Packaging Bags, Mailing Envelopes, Shipping Supplies

I’ve been using the GSSUSA Black Bubble Mailers (4x8) for a while now, and they’ve been fantastic. The build quality is solid—strong adhesive, thick material, and just enough cushioning to protect small, fragile items without adding bulk. The matte black color gives a professional, clean look, which is a nice bonus if you’re shipping for a business or side hustle. They seal tight, don’t rip easily, and hold up great during shipping. I’ve never had an issue with items arriving damaged or the envelopes tearing in transit. Highly recommend these if you’re looking for reliable mailers that get the job done right.

Pretty good quality bubble mailers, perfect for selling on my what not eBay and other places easy to use and really durable oh very happy 🙂

Cheap and thin but work exactly for what I need them for!

I needed a padded envelope for shipping Cloisonné pins to clients and these were the right size and work well. I like it that they are black because I attach a white label with a logo and the result looks good.

The color is so pretty, so vibrant. Durability value for money is good. This is not see-through. The color is rich. Perfect for mailing and using the 4 x 6 thermal shipping labels.

I've used these for 2 years now. These 4x8 bubble mailers feel pretty sturdy, and the adhesive works really well—once you seal them, they stay shut. For small items, they definitely get the job done. The only downside is that they’re a little tight along the sides where the vertical seams are, so the usable space inside is slightly narrower than expected. Not a major issue, just something to be aware of if your items aren’t super slim. Overall, still a solid product and worth 4 stars.

Good quality

Good price and decent quality. A bunch of customers received half of the amount they ordered (myself included) due to a mix-up that I believe has now been fixed. I reached out to them and they were able to fix my problem in a timely manner. Just placed my second order :)

Good seal, nicely padded. Bright so easily spotted if dropped in sorting office
