Just what I needed

I bought these to do meal mixes for quick mixes. Everything is dry that goes into them, so there is no need to pressure can the mix, therefore I'm uncertain how they actually pressure seal. But I do like these. There is no narrowing of the top of the jar neck and that makes it nice to pour in dry ingredients. The glass is heavy, another plus for dry mix storage in cabinets. I will order again as needed.

My favorite locally sourced jars.

I have only had 2 lid failures from the lids. This is 2 too many because I never had lid failures until about 5 years ago. But the jars themselves, these a very nice for locally sourced jars. I just wish Walmart would keep better stock year round. They don't pay attention to those of us who can year round.

GR8 price for 16 oz Mainstay Mason Jars! DELIVERED

I answered affirmably on all counts. Although I have never used Mainstay in canning or water bath canning foods with them. But here they are and I plan on putting them into action and pressure canning some chicken I got on sale from a local farmer. A VERY GOOD SALE by the way. Water bath canning is easy to do. But pressure canning is ONE VERY DIFFERENT ANIMAL. I must do the pressure canning in the fall and winter here in Bakersfield. It is VERY VERY VERY HOT in our Summers and I can't bake or can during in our heat. Sometimes PG%26E asks us to cut all power off during the Summer for about 5 hours from 4 to 9 each day to help OTHERS have power. THE GOVERNOR has closed our WATER power and our NUKE power! Not sure yet who "THEY ARE" but I do it anyway. But canning my small amounts of meat I can still have works great for me. Stage 4 Kidney disease is no fun. I think I am still able to consume AIR and WATER and watch pictures of food pass me by giggles. It has been so long I can't remember the smell of bacon cooking or the taste of a good beef hot dog. Oh My bad...! I hope these Walmart brand canning jars and lids function well. If not I will let you know. IF I am known for anything in my reviews I AM TRUTHFUL! Blessing to all for a job well done...always thankful amen
