## Questions & Answers

**Q: Will these fit a small mouth jar?**
A: They would be slightly too big to be functional for a small mouthed jar. They slip down easily to the second protruding groove on the mouth of a small-mouthed jar.I bought some twist on white caps (from walmart) for the few small-mouth jars I have, and only store dried goods in them as I usually can and ferment with the wide mouth jars. Hope this helps.

**Q: can these be used for canning food in a hot water bath to get a vacuum seal or are they just for general storage jars?**
A: I’m not a canning expert, but I don’t think these are for sealing in a water bath or pressure canner. I use them for dry storage. They would also work well to store any kind of food in the refrigerator. It will not keep food from spoiling any better than whatever else you use.

**Q: Do they stretch?  Jar mouth is 4.5 inches wide**
A: I’m not sure of the dimensions of a regular mouthed jar versus a wide mouth but, if 4.5” is a standard wide then, yes, it will fit.

**Q: Is the metal ring included?**
A: No metal ring is included, just the gaskets.
