SMARTBOX portable storage containers can provide a safe, secure place to store numerous household goods or business supplies. However, there are still some things to keep in mind when deciding what should be stored within these containers. Obviously, nothing alive should be kept inside these containers when closed, for any amount of time. This also applies to plants. In most states, it is against the law to have plants in the back of a moving truck, and these containers do apply to the same standards. Also, do not keep any perishable food items in the storage container, not even for a little while.
