Long Moving & Shipping Boxes 18 in x 6 in x 6 in (25-Pack) - Extra

In this review the reviewer finds these long moving and shipping boxes best suited for small businesses, household moves, and anyone needing a compact, sturdy carton for long or narrow items. The single biggest reason to buy is the combination of professional-grade corrugated construction and a 200 lb extra strength claim that gives confidence when shipping heavier or fragile long items. The pack of 25 and flat-packed storage also makes them practical for those who need to store packing supplies before a move or seasonal shipping bursts.

Key Features

• 18 in x 6 in x 6 in internal size: A long narrow footprint that fits items like tools, small sporting goods, and collectibles while minimizing wasted void space.
• Extra strength corrugated cardboard: Built from a fluted corrugated sheet between two liners to provide rigidity, cushioning and resistance to pressure during transit.
• High moisture resistance: The dense liners and smooth face layer improve resistance to light moisture and help maintain box shape in typical shipping conditions.
• Flat storage and easy assembly: Boxes ship flat in bundles so they use minimal storage space and fold up quickly when ready to pack.
• Pack of 25: A practical quantity for small businesses or moves, offering consistent boxes for uniform packing and stacking.
• Carrier compatible: Sized and built for USPS, UPS, and other common carriers, making them a dependable option for shipping.

Who It's For

These boxes are ideal for small retailers, craftspeople, and households that need a long, narrow box for items such as bats, rolled posters, certain food items, or collectibles. The professional corrugated construction and extra strength make them a good choice when packing items that need shock-absorbing cushioning and moderate protection in transit.

Shoppers who need very large or heavy-duty crates, or those packing extremely delicate electronics that require custom foam, should look elsewhere. Also, buyers who require a variety of box sizes in a single immediate shipment might prefer mixed-size sets instead of a 25-pack of identical long boxes.

Pros & Cons

• Flat-packed for space-saving storage and quick assembly when needed.
• Works well with major carriers for standard parcel shipping.

Cons

• Size is narrow and may be too small for bulkier items, so it is not a universal solution for every packing need.
