Over the course of a year I have ordered multiple Bormioli Rocco Fido square jars in several sizes, including: two in this size with the blue lid (33 3/4 oz), a 25 1/4 oz, four in the 17 1/2 oz size, and a 6 3/4 oz. I was so happy to get rid of all my old plastic storage containers (some of which I am sure contained the dreaded BPA) and replace them with these wonderful jars. I use this size to store my medicinal Essiac tea (which I make up by the quart), stews, and coffee beans. I use other sizes to store nuts, homemade salad dressings, homemade condensed cream of mushroom soup (all organic, and so much better tasting in recipes than store bought canned), homemade stir-fry sauce (so all we have to do is measure out what we need, when we need it - so quick and easy!), homemade salsas and 'cowboy caviar,' as well as left over sauces, soups, etc. Hubby takes soup, stew. pasta dishes, etc. in the 17 1/2 oz size to work for his lunches. These jars are also perfect to use for storing sourdough bread starters in the refrigerator. I love that these containers are clear; I can see which container is holding what I'm looking for at a glance. They are attractive, versatile, and easy to care for; made from heavy, quality glass that will last forever when taken care of properly. Although the base is square, the (wide) mouth is round, so any right-sized gasket will work. OfficialFido Bormioli Le Parfait Jar Rubber Gaskets Seals Original From Italy Sealed Pack of 6 are available right here at Amazon, however, if you prefer those. I consider these jars a great investment, and will be getting more. PROS * jars made in Italy from strong, shatter resistant quality glass * versatile - can be used to store wet or dry foods, in cupboards or refrigerator; attractive enough for the countertop * dishwasher safe WITHOUT gasket and metal * lead free * BPA free * replacement rubber gaskets readily available * available in a variety of sizes ( from 6 3/4 oz to 67 3/4 oz - square bottomed and round bottomed, with four different lid color options (clear glass sprayed with organic European varnishes) * more sanitary than plastic storage options; can be sterilized * lasts longer than plastic and other glass products that lack the quality of Bormioli * because they are clear - it is quick and easy to identify what is stored inside * sealed with air tight gaskets ... foods stay fresher longer CONS * a bit pricey, really, but better quality than many other glass options. * I don't have enough counter or cupboard space for all the Bormioli jars I would like to collect COMMENTS: * only the glass is advertised as dishwasher safe. Not realizing this at the time, the first time I washed the jar in the dishwasher I kept the metal on. When I took the jar out after the drying cycle I noticed a weird white powdery residue on the metal, but was able to clean it off. To remedy this, if I do put jars with metal in the dishwasher, I stop the dishwasher just before the drying cycle begins, rinse off the jar metal (to remove all traces of dishwasher detergent residue), put the jar w/metal back in the dishwasher, and let it run through the drying cycle. No powdery residue or discoloration on the metal. * although I'm sure that the jars are airtight when the gasket is new/not worn, I have had some leakage from a jar when tipped to the side after using the gasket only a few times. NOTE: I paid full price for my Bormioli Rocco Fido Square Jar with Blue Lid; I did not receive the product for free or at a discount in exchange for an evaluation. So, why did I take the time to write a detailed review? Because, like you, I rely upon the comments and experiences of other consumers when making an Amazon purchasing decision.
