A complete 1 gallon glass fermentor.
This unit features a lug-finish glass jar with metal lid. Metal lids won't crack or break like plastic lids, and they provide a much better seal thanks to the thin foam liner underneath. Similar to mason jar lids, the metal lid will show signs of rust over time and need to be replaced, but this won't happen for some time with proper cleaning practices.
