Long Shipping & Moving Boxes 20x6x6 in (10-Pack) - Extra Strength

In this review of the 20 x 6 x 6 in long shipping boxes (10-pack) the bottom line is simple: these are a practical choice for anyone who needs a narrow, durable box for shipping or moving long items. The reviewer found that the professional-grade corrugated construction with a 200 lb test delivers noticeable strength and rigidity, making these boxes especially suited for fragile or elongated items. Assembly is quick and the flat-pack storage is convenient, so buyers who value space savings and a sturdy package will appreciate what these boxes provide.

Key Features

• 200 lb test corrugated: Provides high bursting strength and pressure resistance so contents are well protected during transit.
• 20 x 6 x 6 in internal size: A narrow, elongated footprint that fits items like rolled goods, tools, or sporting equipment with minimal shifting.
• Shock-absorbing fluted core: The fluted corrugated sheet between two liners cushions items and reduces impact transmission.
• Flat storage and bundled packaging: Boxes ship tied flat to minimize storage footprint and are quick to assemble when needed.
• USPS/UPS/FEDEX friendly design: Lightweight yet sturdy construction keeps package weight down while supporting heavy contents.
• Pack of 10: Provides enough boxes for small moves, e-commerce shipments, or organized storage without excess surplus.

Who It's For

These boxes suit small businesses, movers, and hobbyists who ship or store narrow, long items and need reliable protection without excess volume. The extra strength corrugated material makes them a good choice for fragile or heavier narrow goods that still require a light overall package weight.

They are less appropriate for very large items or those requiring wide packing space; customers with bulky furniture or very small flat items that need wide surface area should consider other box shapes and sizes instead.
