·Kraft Bubble-Lined Mailing Envelopes: LULUPACK Kraft bubble mailers feature a durable kraft paper exterior and a protective bubble-lined interior, providing reliable cushioning for shipping jewelry, cosmetics, makeup brushes, trading cards, accessories, and other small items. The natural kraft finish offers a clean, professional look while keeping contents secure.

·Self-Sealing Closure: Each mailer features a convenient peel-and-seal adhesive strip, allowing quick and easy sealing without the need for additional tape. The strong adhesive creates a tamper-evident seal that keeps contents protected throughout shipping and storage.

The kraft paper exterior is puncture-resistant and recyclable, while the inner bubble lining absorbs shocks, vibrations, and impacts during transit.

·Product Information: Available in 11 sizes ranging from #000 (4×7 in) to #7 (14.25×19 in), with multiple pack quantities to meet different shipping and packaging needs.

Stocked up before the holidays

Ordered ahead of the holiday rush so I would not run out. Bought several sizes at once and everything shipped fast from the California warehouse. The bulk pricing makes stocking up painless. Ready for Q4 now!

Thanks Andrew! We are glad you are all set for the holiday season. - LULUPACK Team

Very good mailers, minor packing note

The mailers themselves are great - strong, clean, and protective. I noticed a couple of them in the box had slight creases from packing, which is cosmetic only and did not affect use. Would definitely buy again.

Gregory Hall
Reliable for quarterly stock-up

I stock up every quarter for my online store and LULUPACK has been reliable every time. The 11-size range covers everything I ship, from small parts to bulky clothing. The pricing stays fair even as my order volume grows.

Stephanie Turner
Second order - still great

This is my second order and I am just as happy as the first time. Quality stayed consistent and delivery was quick. I have referred two other sellers to this brand already.

Thank you, Stephanie! We really appreciate the kind words and the referrals. - LULUPACK Team

More premium than poly mailers

Switched from poly mailers to these kraft bubble mailers and the difference is noticeable. They look more premium, stand up better in transit, and still keep the package light. My customers seem to appreciate the upgrade too.

Ashley Brooks
The size chart is spot on

The size selection guide on the listing is really accurate. I ordered the #0 for sunglasses and #1 for books and both fit exactly as described. No more guessing and wasting mailers. Makes ordering for different products so much easier.

T
Thomas Wright
Lots of mailers for the price

You get a generous quantity for the price compared to what big-box stores charge. Every mailer in the box was usable - no defects. I use the smaller sizes for car parts and accessories and they have held up great.

N
Nicole Adams
Great value for a small business

We are a small supplements brand and packaging cost matters. These mailers are well priced, especially with the bulk discount, and the quality is better than what we used to get from other suppliers. The bubble lining protects our bottles during transit.

K
Kevin Martinez
Perfect for A4 documents

We use these in our office for mailing contracts and documents. The #2 size fits A4 paperwork perfectly and the rigid kraft exterior prevents folding and creasing. Much nicer than the flimsy paper envelopes we used before.

Fast delivery from California

Needed mailers quickly for a rush of orders and these arrived in just two days from the California warehouse. Quality is great - thick kraft paper and a strong seal. Being able to get them this fast domestically is a big reason I keep ordering.

D
Daniel Kim
Solid mailers overall

These are good, dependable mailers at a fair price. The kraft finish looks clean and the bubble layer does its job. I took off one star only because I would love more variety in the kraft style - maybe different sizes of the same design in one variety pack.

M
Megan Foster
T-shirt shipping made easy

I sell graphic tees and the #2 size is a perfect fit for a folded t-shirt. The mailers are thin enough to keep postage low but protective enough for regular USPS handling. The tamper-evident seal is a nice touch for customer confidence.

Ryan O'Connor
Consistent quality, order after order

This is my third order and the quality has been consistent every time. The kraft paper is durable and the adhesive seals firmly. Only reason for four stars: I wish the larger sizes came in bigger bulk packs, since I go through #4 fast.

L
Lauren Baker
Protects my makeup brush orders

I ship makeup brush sets and the bubble lining gives me peace of mind - brushes arrive without a scratch. The #2 and #3 sizes fit my kits perfectly. The mailers look clean and professional, exactly the image I want for my brand.

C
Chris Novak
Customers love the kraft look

I have had several customers mention that the natural kraft packaging looks more eco-friendly and premium than plastic mailers. They are recyclable, which matters to my audience. Protection is great too - nothing has arrived damaged yet.

A
Amanda Carter
Great quality and fast shipping

Ordered the #5 size for multi-item orders and they are roomy and tough. Delivery from the California warehouse only took two days. Quality is consistent across the whole box - no thin spots or weak seals. Will be reordering.

B
Brian Wilson
Saved us money on postage

We ship phone cases and small accessories. Switching to these lightweight mailers actually lowered our average shipping cost because we could move orders down a weight tier. The self-seal closure also sped up our packing line. Win-win.

J
Jessica Lee
Bought these for my clothing store

I sell hoodies and sneakers online and the #3 and #4 sizes fit them well with room to spare. The mailers have held up through multiple shipments with no tears. Being able to order all my sizes in one place from the California warehouse is really convenient.

M
Michael Thompson
Perfect for my Etsy shop

As an Etsy seller I need reliable, lightweight packaging and these deliver. I use the #0 size for sunglasses and the #1 for folded crafts. Lightweight means lower shipping costs for my customers, and the kraft exterior is nice and rigid.

E
Emily Rodriguez
Finally, professional-looking mailers

I run a small cosmetics brand and used to ship in plain white poly bags. These kraft mailers look so much more put-together - customers have actually complimented the packaging. The inner bubble layer keeps bottles and jars safe. Highly recommend.

D
David Chen
Sturdy and affordable

Ordered these for shipping trading cards. The #1 size is the standard card mailer size and they arrived perfectly. Sturdy enough that cards don't get bent even on longer trips through the mail. Price is very fair for the quality.

S
Sarah Mitchell
Great mailers for my jewelry business

I ship jewelry and small accessories, and these kraft mailers are perfect. The #000 and #00 sizes fit earrings and pendants snugly, and the bubble lining keeps everything protected. The peel-and-seal strip means I don't need tape, which saves me time on every order.

Thank you so much, Sarah! We are glad the mailers are working great for your jewelry orders. - LULUPACK Team
