At 21 inches square, these corrugated shipping boxes are a versatile option for a variety of merchandise. Load them with everything from books to decor items—each box can support a maximum of 65 pounds safely.
The edges of these corrugated shipping boxes are rated to withstand up to 32 pounds per square inch of pressure without collapsing, so you can stack them without damaging the contents. The strong, durable corrugated fiberboard sides absorb force without tearing, so they remain intact during loading and delivery.
Don't overload your shipping supply room—these boxes come in bundles of 15, so you can order only as many as you need. They ship in a flat package, which doesn't take up a great deal of storage space. The boxes fold together quickly and tape shut easily without the need for complicated instructions.
