It can be washed and used again. - AIRTIGHT SEAL - Kimchi container made with an airtight silicone seal, it ensures there will be no contamination to your food and ensures no oxygen gets in. This prevents mould from growing. - ONE-WAY VALVE - The valve automatically releases the built-up gases from the fermentation process, so you can avoid the hassle of muslin cloths! It is the most convenient way to release the gases without letting in contamination or oxygen. - EASY TO USE - Prior to filling with food, ensure the kombucha jar is clean and dry. Push food down to eliminate air, then seal with the airtight lid. No valve management required: the unique one-way valve in the lid allows built-up fermentation gases to be released automatically. These fermenting jars fit well in the fridge, and can be stored at room temperature. - FOOD-SAFE - The fermentation jar is safe for food. Simply add your food to create bacteria making it a natural probiotic. - EASY TO CLEAN - Simply hand-wash these pickling jars with warm, soapy water; avoid sterilising with hot, boiling water.
