Prepare and preserve all your favorite foods with the help of our Mainstays Glass Lock Lid Jar. Featuring a glass build with metal hardware and a soft, flexible seal, this handy kitchen storage tool makes it easy to keep a wide variety of foods, seasonings, and spices fresh and easy to identify. Its durable metal locking hardware ensures a tight clamp is kept on the jar while the flexible seal allows the lid to perfectly squeeze against it and create an air-tight closing.
