8.5x12 Inch Black Bubble Mailers

Heavy thick high quality bubble mailer with a extreme adhesive seal. Look no further. These are the ones you want

I like the color and they feel very sturdy and stiff. Fits a little roomier than some other size 0 bubble mailers I’ve purchased in the past, which is a good thing, they’re the perfect size for my product. Will buy again.

We received the product and were initially confused by the sizing. It’s advertised as 8.5 x 12", but in reality, the envelopes are only 8.5 x 11". The manufacturer included the flap in the measurement, which is unusual — and this detail was only visible in one of the product images. Everywhere else it says 8.5 x 12". We contacted the seller right away. What really stood out was the excellent customer service. They responded promptly, updated the product title and description to make things clearer for future customers, and were very focused on finding a good solution. Communication was quick and straightforward. As for the envelopes themselves: they appear well-made and the black color looks nice. The bubble padding could be a bit thicker, but for our purposes, it's totally fine.

Great value, quality, and price!

I am currently clearing out my closet after a 120-pound weight loss journey, which means parting with my collection of 50+ vintage 1990s Nicole Miller silk shirts and my oversized 3X and 4X YIUME shirts. I was terrified of shipping these delicate silks, but these Fuxury #5 mailers have been an absolute lifesaver! The 10.5x16 size is the "Goldilocks" fit—large enough to fit a bulky 4X shirt without struggling, yet perfectly sized to keep a folded silk blouse flat. My biggest concern was weather protection, and the waterproof exterior gives me total peace of mind that a rainy delivery day won't ruin a vintage piece. They are incredibly lightweight, which keeps my shipping costs down, but the bubble padding feels sturdy enough to prevent snags. The self-seal strip is also super "grabby," so I don't have to waste extra tape. If you’re selling clothes online, these are a 10/10!

I use these to ship my Poshmark and Depop sales. I like that they have a bubble interior and the adhesive to close them is very strong. They’re good for thin lightweight things, but the bubble part is not super thick . They feel pretty good quality though.

Exactly what I needed. Thanks!

These are true to size.They hold a lot of stuff and I use them to ship during october month.And my customer is definitely love these very sturdy.The tape last and it stays sealed until it arrives at the customer's doorstep. It is waterproof very thick.The bubble wrap keeps the product safe

I love the quality of these mailer bags. I remember ordering one from SHEIN and there was a huge difference. These are thick and will keep your product secure.

I run a small business and buy a lot of these. The ones I usually get were out of stock so I went with these. The outside bubble walls are kind of thin and I worry about their durability. Would not buy again.

Went through mail fine. I got a package return to sender and it held up well. Will recourse as needed.

the outside dimensions of the envelope are 11.25 x 15. The max size for a "letter size" with Canada Post is 10.62 x 14.96 inches.
