We haven't discovered any water in our house for 1.5 years. When opening the box, however, you have to be careful that any water that may have collected on the box does not flow in

The box is neither waterproof nor moisture-proof.
However, the box protects the contents from rain and snow without any problems.

The lid is made of one piece and is slightly larger than the box, so the water can run off without getting into the box.
