Bormioli Rocco Quattro Stagioni Vaso jar, 50.75 ounces, 1500ml. Bormioli Rocco Quattro Stagioni jars and lids combine the traditional advantages of safe preserving with the guarantee of modern vacuum packing. It is a safety that "just any" jars cannott guarantee. A vacuum that YOU SEE and CAN FEEL because, after completing the vacuum preserving process correctly, the indent formed in the middle of the lid guarantees a perfect vacuum seal. The result is always controllable thanks to the characteristic popping sound you hear the first time you open the jar. That is why Quattro Stagioni jars, specially designed for homemade preserves but with all the features of industrial processing, have always been a favorite with people for whom preserving is an art, as well as an enjoyment. This Quattro Stagioni canning jar is intended for long term preservation of food, and comes with a one piece metal lid to seal the contents. Replacement lids are also available. Lids are BPA free.
