Fermentation Jar with Water Seal - The fermentation crock jar features a water-seal design that creates a stable environment for fermentation, including sauerkraut and wine brewing. This helps prevent odors, dust, and chemicals from leaching into the pickles. 2.5L and 1.5L Glass Jar with Lid - Available in two practical sizes: 2.5 liters and 1.5 liters, each with a lid. Suitable for homemade pickles, kimchi, vegetables (onions, ginger, garlic, cucumber, carrots, cabbage), canned peaches, jams, jellies, tomato sauces, brewing, preserving wine, and more. Durable Glass Pickle Jar - Thickened glass construction for durability and safety. The thick glass is designed for years of use in homemade kimchi, pickles, and wine brewing, or for storing dry foods. Easy to Use and Maintain - To create an airtight seal, pour some water around the bowl lid channel. This prevents outer dust and air from entering the jar. Wash with your usual kitchen detergent, then dry the jar completely and store in a dry place for next use. Remember to add water into the bowl lid channel every week.
