Large Shipping & Moving Boxes 20 x 16 x 12 in (5-Pack) - Extra

In this review of the Large Shipping & Moving Boxes 20 x 16 x 12 in (5-Pack), the bottom line is simple: these cartons are built for customers who need sturdy, dependable boxes for moving or shipping medium to heavy items. The reviewer found the pack of five to be a practical balance between storage footprint and capacity, and the most compelling reason to buy is the professional-grade corrugated construction that offers higher resistance to pressure and moisture, making them suitable for fragile or dense contents.

Key Features

• Size and capacity: The internal dimensions of 20 x 16 x 12 in provide ample room for medium-sized household items and bulky goods while remaining manageable to lift and stack.
• Extra strength construction: Made from professional-grade corrugated cardboard with high density and rigidity, these boxes support heavier loads without collapsing.
• Shock-absorbing cushioning: The fluted corrugated sheet between two liners offers a cushioning effect that helps protect fragile contents during transit.
• USPS/FEDEX/UPS friendly: Designed as an approved style for common carriers, they are a lightweight option that still supports secure shipping.
• Flat storage and quick assembly: Boxes ship flat in tied bundles for minimal storage space and fold together quickly when needed.
• Neat appearance: A smooth face layer and crisp fold lines make sealing and labeling straightforward and tidy.

Who It's For

These boxes are a good match for homeowners moving medium-sized items, small businesses shipping products that need heavier-duty protection, and anyone looking for shipping cartons that balance durability with a light package weight. The cushioning corrugation and moisture resistance make them suitable for electronics, kitchenware, and other fragile items when combined with appropriate internal packing materials.

Those who should look elsewhere include buyers who need very large wardrobe or appliance cartons, or customers who require single-use ultra-cheap boxes for light, one-way moves; this pack is sized and built for repeated handling and somewhat heavier contents rather than minimal-cost disposables.

Pros & Cons

Cons
