I purchased these for short-term dry goods storage as well as using them for container gardening. Buckets themselves are sturdy enough and the lids are gasketed and create a decent seal. I buy beans, rice, flour, etc. in bulk and store the excess in the buckets. These could easily be used for long-term storage using sealed Mylar bags as a liner along with O2 absorbers.
