However, it is the ideal solution for vacuum packing and storing liquids such as soups, stews, sauces, and chili in your refrigerator or freezer.  It also helps preserve the texture and flavor of refrigerated meats and vegetables. Dry foods such as nuts, grains, and cereals may be vacuum packed and stored on your pantry shelf.   TheThriftyVac Mason Jar Lid allows you to quickly vacuum pack your food, and quickly release the vacuum to extract your food and repack the jar, all while keeping the metal lid in tack.

However, the system can be easily disassembled and reassembled by hand should you so desire.The ThriftyVac Mason Jar Lid comes in two different sizes to fit standard and wide-mouth Mason jars.The ThriftyVac Mason Jar Lid is sold in packs of five.
