• MVP LIDS ARE DESIGNED TO HOLD 80-85% VACUUM TO EXTEND STORAGE LIFE: Store juice, perishables and dry goods 2-8x longer. Purpose built, reusable, and dishwasher safe. Each set includes 6 wide mouth mason jar lids with valves.
• ENGINEERED TO LAST - FEEL THE QUALITY: The MVP lids are designed for customer satisfaction and engineered for years of use. Unlike traditional canning lids, these triple thick 0.4mm stainless steel lids feature a custom silicone gasket and valve. Together these form a near-perfect vacuum seal. The MVP lids can hold vacuum for weeks or even months!
• SIMPLE VACUUM DETECTION TECHNOLOGY: the vacuum valve opens at the touch of a fingertip—no tools, no spilled contents, or damage to the lid. just push the valve sideways and listen for the “whoosh" of escaping vacuum.
• LEAK DETECTION AT-A-GLANCE, THE INDENT IS THE PROOF: The top of the MVP valve is domed; when vacuum is present the dome is drawn down inwards towards the jar. Simply look to see if the dome is down or up.
• FRESHER FOOD & EASY FERMENTATION – Our stainless steel fermenting lids for mason jars fit wide-mouth jars, keep food and juices fresh while doubling as durable lids for kombucha, sauerkraut, and all your fermenting needs.
