Complete Fermentation Kit: Includes a 32 oz fermenting jar, fermentation weights, fermentation lid, and airlock. Contains all essential components for fermentation—no need to purchase additional items or worry about compatibility. Premium Quality Materials: The 32 oz jar is made of thick glass; fermentation weights are evenly weighted; the wide-mouth fermentation lid is stainless steel; the airlock is made of food-grade polycarbonate (PC). These materials support safe and efficient fermentation. Easy to Use: Fill the one-way airlock halfway with water to allow carbon dioxide to escape while preventing overpressurization. The airlock also blocks external air, maintaining a controlled fermentation environment and improving success rates. 2-in-1 Functionality: The fermentation lid includes a silicone plug—remove the airlock after fermentation and seal the jar for storage. All parts are dishwasher-safe and reusable. Versatile Use: Ideal for making kimchi, sauerkraut, pickles, and other fermented foods. Suitable for beginners and experienced users alike—supports safe, healthy food preparation and preservation. Color: Transparent Material: Glass + Metal Package Contents: 1 x Mason Jar Fermentation Kit
