Letterhead Cardboard Boxes 11 1/4 x 8 3/4 x 4 in (25-Pack) - Extra

In this review the reviewer finds these letterhead cardboard boxes ideal for small business shipping and household moves; the single biggest reason to buy is their extra strength corrugated construction that protects contents while remaining lightweight. The pack of 25 boxes at 11 1/4 x 8 3/4 x 4 in internal size suits small but bulky items and provides consistent protection for long-distance carriers like FEDEX and USPS. The review highlights ease of assembly, flat storage convenience, and reliable cushioning from the fluted corrugated sheet.

Key Features

• Professional-grade corrugation: The fluted sheet sandwiched between two liners gives a high level of rigidity and resistance to pressure for safe transit.
• Extra strength construction: Designed to support heavier loads while keeping package weight low, making them practical for repeated shipping.
• Moisture resistance: The boxes have good resistance to moisture and maintain structural integrity during typical shipping conditions.
• Flat storage: Boxes ship tied in bundles and stored flat, saving space until quick assembly is needed for packing.
• Consistent internal size: The 11 1/4 x 8 3/4 x 4 in dimensions provide predictable storage capacity for books, dolls, small electronics, and other items.
• Universal compatibility: Sized and shaped for common carriers like FEDEX and USPS and suitable across small business and household uses.

Who It's For

These boxes are best for small business owners, online sellers, and households who need a dependable, uniform box for shipping medium-weight items. The pack of 25 is a practical bulk buy for recurring shipments, storage of seasonal items, or moving smaller items such as books and collectibles.

Those who need very large crates, specialty insulation, or rigid plastic containers for long-term outdoor storage should look elsewhere, since these are corrugated cardboard and designed for internal shipping and storage rather than heavy outdoor exposure.
