The first night in a new home can be overwhelming. Amidst stacks of boxes, finding essentials can be a daunting task. That's where the "open first" box comes in. This box should contain everything you'll need immediately upon arrival, from toiletries and pajamas to important documents and some snacks. Think of it as your survival kit for the first 24 hours. Having this box on hand ensures that even if you're too tired to unpack everything, you'll have all the essentials within easy reach.
