The fustis offered here are made from the finest available Italian 18/10 stainless steel under the best possible quality controlled conditions. All joints are TIG (Tungsten Inert Gas) welded to insure completely smooth interior and exterior surfaces to prevent matter accumulation. These fustis are not the more common and less expensive folded metal containers that are constructed like tin cans, and have seams that can trap food particles, leading to bacterial contamination. The NSF (National Sanitary Foundation) liters have a special seal and lid cover and has been tested by NSF laboratories. Fustis add more class to your kitchen and is a perfect gift for the chef or cook who has everything.
