12 x 12 x 40 Tall Packing Boxes 15/Bundle

These 12x12x40 inch tall packing boxes are perfect for storing and moving common household items. They're made from high - quality 200#/ECT - 32 kraft corrugated material, ensuring durability. Sold and shipped flat in bundles of 15, they're convenient for storage and transport.

How to use: First, unfold the box and fold along the creases to form a rectangular shape. Secure the bottom flaps with packing tape. Then, place your household items inside carefully. You can stack lighter items on top of heavier ones. When packing fragile items, use bubble wrap or packing peanuts for extra protection. Close the top flaps and seal them with tape. Attention: Don't overload the box beyond its capacity to avoid tearing. When stacking boxes, place heavier ones at the bottom. Maintenance: Store the flat boxes in a dry place to prevent moisture damage. If the box gets dirty, you can wipe it with a dry cloth.
