The inside of the container is perfectly designed to keep all of your outdoor gear dry and well-ventilated. For easy access, it is built with hydraulic automatic opening mechanism.

In addition to its extra-large capacity, this storage container is extremely durable. The entire storage container is weather-proof. Most importantly, it is covered in a UV-protected resin, which prevents the container from bleaching in the sunlight.

Another great aspect of this Keter storage container is that it has a thoughtful, contemporary design that can fit into any patio. Moreover, it is designed with a flat top so it can double as a bench for two people.

If you have a small patio, this is the perfect storage box for you. Its small and compact size means it can fit well in many areas without looking out of place. However, do not be fooled by its small size. While it is small, it is definitely strong. It is specially designed to withstand abuse from the weather and prolonged sun exposure.
