What fits this size

  • Consolidated B2B shipments of smaller packed items
  • Pillows, cushions and other large soft goods
  • Mixed replenishment orders to your own stores
  • Light, bulky products such as lampshades or foam packaging
  • Kitting: several finished products packed as one order

Worth knowing. This is single-wall board. Bulky and light is fine, but a dense, heavy load in a carton this large puts the strain on the bottom flaps. Ask us for a firm view on board strength before ordering for anything heavy, and expect dimensional weight of about 28 lb.

Consider a different size

Honest guidance rather than an upsell — the wrong size costs more in failed parcels than it saves per unit.
