Works Great in Mason Jars

I've always wanted to try fermenting vegetables, since they are good for your health.  Crocks are very expensive and one needs weights to use in mason jars.  I'm so glad I found these.

Used these on Mason Jars for my wedding and they were great! Although, the chalkboard pen that came with it was not good.  Luckily, I had bought extra pens just in case.

Perfect addition to the set of 12 mason jars I got. Shipped in 2 days. Great price for 12 lids

I love this because you only have to keep track of one piece. I love the mason jars, but if you don't use it for canning, keeping track of the lids can be
a nuisance. What makes this special, is that it's easier to use then a regular jar lid because you don't have to screw off the lid, just pop the top and pour out your food.  The one thing I would like to see the company do is a wide mouth version. However, this also fits non mason jars as well.

This makes any small mouth mason jar a shaker, pourer or small item dispenser.  I'm now using my antique jars for more than display and love this item

Works great! I put the left over latex in a mason jar so it doesn't leak.

I love drinking out of a quart Mason jar. These lids keep my drink covered. The straw is sturdy. It's so fun to use!

Love these lids to "dress up" my mason jars for drinking. So cute! I have read some 1-star reviews saying they don't fit standard jars, but mine fit all of my jars just fine.

These worked great with my wide mouth mason jars and the Pickle Pipe Silicone Lids&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Pickle-Pipe-One-Piece-Silicone-Waterless-Fermentation-Airlock-Lids-for-Mason-Jar-Fermentation-Wide-Mouth-3-Pack/dp/B01726CJ9Y/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Pickle Pipe - One-Piece Silicone Waterless Fermentation Airlock Lids for Mason Jar Fermentation - Wide Mouth - 3 Pack</a>.  They were easy to insert, easy to get out (with the help of a knife to push down one side, and really easy to clean.  And during the fermentation process, carbon dioxide bubbles were easy released around them.

You should definitely keep the box they came in to store them.

Love these little mason jars. I will be using them as Christmas gifts and filling them with bath salts with essential oils. I've decided I need more so I will be ordering more. Love them! Thank you!

These are great jars. They seem to hold a bit more than comparably sized mason jars. I also like the fact that they have solid one-piece lids, which are better for storing items which I use a lot (no messing with two pieces of the usual mason lids). They fit onto Kerr and Ball wide-mouth jars too, so I can use them on slightly smaller jars for spices, etc. that I use a lot.

I also like the design on the jars. Very pretty.

Great product. Very fast shipping.

I use this mason salad jar daily to bring salads to work. Previously I was utilizing glass jars, but they are a little heavy to tote back and fourth with a 34oz glass jar. I love that under the lid it has a container to hold salad dressing. This container and the lid to the mason jar do not leak at all. I have been using this jar for about a month now and wash it in the dishwasher and have not had any issues. I wish it wasn't as pricey though as I would love to order more!

I purchased these in both sizes & they fit perfectly into both size mason jar lids.  They provide an air tight seal for transporting liquids.  Make sure you do not over tighten the lids or they will be nearly impossible to remove!  I've used these daily for about 6 months now & they look like the day they were purchased.

I use my wide-mouth mason jars for so many different things -- none of which is canning!  I use them for storage in the pantry and in the refrigerator, for making vegetable ferments and milk kefir and sourdough starter and so many other things.  They are easy to use and to clean and of course do not rust.

Love these! They work great! I am glad I read other reviews saying to cut the ends off... they were long for my mason jars, which will be good for some I'm sure! We are using all 3 and haven't had any problems!
