Are these lids really one-time use, or is this just a suggestion by the manufacturer?

If you're really going to use them for water bath or pressure canning, then yes definitely only one use. Metal lids will only make a sterile seal the one time. This isn't specific to this product, though--it's pretty universal in canning (except for the Tattly lids which are re-useable). But you can use them as many times as you want after that if you're using your jars for non-canning purposes like storing rice or nuts or buttons or whatever. I keep a big bowl of used lids for when I'm not actually canning, and then when I break out the canner i also break out my boxes of unused lids.

The lids are one time use for canning as suggested in the canning blue book and most people I know use them once, The rings are reusable.

Hi Robert. I had an issue with the Wolfgang Puck lids shattering. I got them in 2010. I do not know if the problem has be rectified. They did replace the two lids that shattered. If I had it to do over again I would not buy this product. My reasoning it different than your question. I do not like it that the pans have to be hand washed and I will return to other brands. Much to my suprise I prefer teflon.

I've had these containers for about three years and I don't think I've ever had one of them leak. My family uses them everyday and we always wash them in the dishwasher including the lids, often on heated sanitizing cycles and I've not experienced any changes in the way the lids fit, unlike some other containers we've tried before that warp easily. These don't -- the lids continue to seal really well even after years of use. I've never had a lid come off accidentally and we've toted them just about everywhere.

The white lids that I received are all one piece...I'm not sure if they seal...I got them because I can label the white lids with dry erase markers to keep contents in the fridge for a week or less.

I have used this same size jars for three years and I am using the same lids. They seal tight with a solid loud pop each use. I do not plan to buy replacement lids anytime soon. I love these jars!

Yes, they have a little tab you press to remove the lids. I think they are the right amount of sturdiness. I did drop one that had been frozen and it cracked, but that didn't surprise me. They worked great in the freezer and fridge.

I would not suggest it..I think they would break down and contaminate food like plastic..and they are air tight . Most lids need to be vented in microwave...Just my opinion

I have used these lids for several months now and they work just fine. Do not try to use lid more than once or you will have grounds get through. You may have to watch to make sure when putting than on that it is evenly and completely snapped in place. I wash out my pods and rinse the filter gently then let dry for 24-48 hours before refilling them and inserting lid. Depending on the quality of the pods filter, one can reused pod 3-5 times before the filter becomes too week. Some pods are tighter than others and may crack preventing multiple use. If you get filterless pods as in cider or some use instant coffee methods, you can also buy insertable filters from this company too. Hope this helps!

They are light weight and well made. The lids are plastic and while in use are not tighly sealed. You should be OK.

The lids stay on. There is a tab at one of the corners (not shown in the picture) that you sue to take off the lids. Otherwise, it would be a little hard to get them off. However, it is easy if you use the tab. So they stay on very well but are also relatively easy to take off.

Yes they are. I just love my set. To keep them like new all you have to do is season them twice a year by coating the inside with cooking oil, heating until they begin to smoke, let them cool, wipe out excess oil and they are good to go with no sticking great cooking! The glass lids are so perfect and make it so easy to keep an eye on what's cooking!

They are new. When mine came, the lids had never been put on the containers before, and required a lot of muscle to jam on the first time. At that point the lids stretched, and now function well, tight seal.

They do scrape them up a bit if the jar lid is tight & you're trying to get a good grip. I'm not sure if I would consider them "un-reusable", just scraped up.

They are quite sturdy, but I have no idea of the needs of a professional kithcen. If the lids, which are secured by a strong wire arrangement were to be opened many times a day, there might be a problem, but I can tell you these are the best around that I have seen

I'm not a professional and so mine are hardly used. I just checked after months of not using them and they certainly seem okay. My suggestion would be to keep the lids tightly closed and to possibly layer a small piece of Saran wrap over the top of the paint to further keep it moist. Alternatively, you can probably always moisten any dry paint, if necessary, by wetting your paint brush or sponge, then work the moisture into the paint. I hope this helps!

Yes the lids seem airtight to me. They have screw on grooves that secure on pretty well. Interesting idea to use them for dry snacks. Will have to try.
