Question: How wide is the mouth of the jar?
Document: I just added this jar to the two that I already have on my counter (they're over 15 years old now). I use them to store flour and sugar - and they're perfect for that. The jars are both attractive and practical - and definitely keep items free of mealy worms, etc. that can usually work their way into most containers. Attractive, affordable, and long-lasting. Le Parfait jars are perfect additions for your kitchen!
I received my jar no problems the seal in side jar. A very attractive jar I have several sizes this is my first 3 liter and its a nice large size. I will be buying more of these in the future. They are a bit pricy so I watch for a sale. These are so much better than others out there and i have tried many. I will use mine for dry storage, brown sugar, chocolate chips,tea,and many other food items. They are Beautiful on the counter.
I love these jars. I do have a question, hope someone can help me. The item description states: "Some people also use Le Parfait jars with special gaskets to make fermented foods; in this case, the gasket allows gas to escape from the jar, but not to enter it." Does anyone know where to find those gaskets? I looked on the Le Parfait site, couldn't find them. May have missed them, not sure. I have looked lots of places. Thanks for your help.
I have brought different sizes of Fido(10 jars) and Le Parfait(20 jars) Terrine Glass jars from a wholesale seller "wholesaleglassbottles"Le Parfait jars are thicker and heavier than Fido jars. I'm not sure if thick glass means stronger.The Le Parfait Terrine Jars latches don't stick out after closing the lid they are flush with the jar.one advantage of Terrine jar is that it has no "neck & shoulder" so a frozen food will come out like a thanksgiving cranberry jelly.
Works well. Seals tight. Easy to take completely apart to clean. I use it mostly for homemade juice with macerated fruits. Also made limoncello in it. Doesn't pick up off odors like plastic beverage containers.
Not sure if they were missed in the packing, or if I didn't look hard enough, or what. For anyone else running into this problem, the gasket size is not stated in the product description but I think it will take the 100 mm gasket.
Love these Jars, good quality. Using them for flour storage. A bit pricy but healthier than plastics. Purchased other sizes as well.
I'm in my 60s, and I've been using Le Parfait jars since I was 20. These 3-liter jars are bigger than I expected from the factory specs... and the openings are plenty big for easy washing of the insides. Perfect for storing 5 lbs of Espresso beans in a couple or three jars. My original seals are still going strong... but I'll have to do some research to find extra backup gaskets for these.
I use for flour to keep airtight seals in my cupboards. Beautiful jars that work awesome! This one is huge so make sure you have a place for it before you buy!
I have purchased 2 of the 2 liters as well. I use those for brown sugar. I got the 3 ltr to hold bulk candies in. The seals are perfect. Everything I put in these jars stays fresh. Very pretty out on a counter top or in an open pantry. Arrived on time, in perfect condition. I will buy from this seller again.
