"Wind and watertight" is the most-used phrase in container sales, and most buyers don't know what it does and doesn't promise.
WWT means the container keeps out wind and rain: doors seal, roof doesn't leak, walls are intact. It does **not** mean pretty. A WWT container can have dents, surface rust, and faded paint and still do its job perfectly for storage.
Where buyers get burned: sellers who use WWT to describe containers that don't actually seal. The test is simple. Stand inside with the doors closed. Any daylight through the walls or roof means water gets in too.
