Have used my set of these for years and love them. They are by far the best lids for Mason jars that I've ever found - and I have done my research on the subject! They are very well made; thick & sturdy not flims, fit jars perfectly, and are extremely durable. They even manage to be almost totally stain-proof. I've ruined 1 out of 40 in about a decade of use on my set! When tightened fully they seal perfectly and don't leak at all. The only thing they can't do is hold tight when a jar is filled with boiling hot liquid and jiggled. In that case they will loosen & dribble. Other than that they go above & beyond meeting all my very high demands. (Posted on 12/31/2012)
the lids seem good and sturdy. Oly thing I haven't used them yet, because deceivingly from the picture on int. they were too large even for my big ball jars.
big jars but narrower top I guess.
I must order more
Thank you. (Posted on 12/5/2013)
I've been using Mason and Ball jars for food storage for years. These plastic lids come in two sizes and are a wonderful fit for all my jars. The smaller ones fit spaghetti sauce jars too. They wash easily and don't rust, like the metal lids. I don't think these lids are meant to be used for canning, but they work great for food storage. (Posted on 1/20/2014)
