150-Pack 9×6×2 in Black Corrugated Small Shipping Boxes (Mailers)

Product description

Box dimensions and pack: Each kit contains 150 rectangular mailer boxes shipped flat for compact storage. Inner measurements are 8.75 inches long × 6 inches wide × 2 inches high; external dimensions measure approximately 9.25 × 6.06 × 2.06 inches.
Materials and finish: The mailers are produced from 200#/ECT-32-E corrugated board in solid black on both the interior and exterior faces for a sleek presentation. The material is recyclable and designed to be eco-conscious while maintaining strength.
Design and protection: These small mailers fold into a horizon-style flip-top box with a lid and integrated dust flaps that help secure contents and reduce the need for tape. The folded construction gives doubled protection at the front and side panels, helping resist crushing during transit.
Weight and handling: Each unit is lightweight to help minimize shipping costs while remaining rigid enough for many lightweight products. They fold up in seconds with no glue, tape, or staples required for basic assembly, making packing quick and repeatable.

Reviews

  1. Susan fetterman 5/5

    Well made and reliable

    Simple, well-constructed boxes that hold up during handling. Sturdy.

  2. T R 5/5

    High quality as advertised

    Matches the listing and feels high quality. I will buy them again.

  3. S. Gallon 5/5

    Small but sturdy mailers

    Compact boxes that are easy to put together and durable. I used them to ship items sold online with no issues.

  4. Brown Sugar 5/5

    Solid and good value for candle shipping

    Very sturdy and the dimensions fit my glass candle containers well. The board thickness is what I needed and they offer good value. I’ll reorder — the black finish works well with my branding.

  6. heather 5/5

    Consistently reliable

    I’ve reordered these multiple times because they meet my needs every time. The included coupon is handy — I just keep forgetting to redeem it!

  7. momma of 10 5/5

    Attractive, easy to fold

    They fold up easily without tape and look nice. I placed a single book in each with a small sticker and they were perfect. Good price for what you get.

  8. Robbin 4/5

    Works for lightweight but bulky items

    I gave four stars. One carrier flagged them as not double-wall, but another carrier had no issue. They fit my resin chess set board with some bubble wrap and did the job.

  9. Marie 5/5

    Exactly as listed

    Nice box and good construction. Matches the description.

  10. cantrips 3/5

    A touch thinner than earlier stock, still usable

    Compared to my older pack these are roughly 15% thinner and have a little more give after folding. They still protect items reasonably well, though I preferred the older, firmer version and may reconsider future purchases.

  11. Chsgrl76 5/5

    Slim but practical; fits 4×6 labels

    These are thinner than typical E-flute but remain reasonably rigid. A 4"×6" shipping label adheres perfectly and the dust flaps add extra security so I use less tape. Good option for small rings and similar items.

  12. Orazio Galli 5/5

    Perfect size and simple assembly

    These are the exact size I wanted, assemble in seconds, and are well made. I plan to order more.

  13. CynthiaS 5/5

    Lightweight and functional for jewelry — note on size change

    Update: the maker altered the interior size to about 4"×4"×2" on newer batches. I craft and sell jewelry and originally chose these because they’re very light (helpful for shipping costs) and fit two 3"×3"×1" jewelry boxes stacked. Still useful, but be aware of the recent size tweak.
