3 Pack Regular Mouth Mason Jar Flip Cap Lids with Handle for Ball Mason Jars, Airtight and Leak-Proof Seal, Easy Pouring Spout (Jar Not Included)

Without using 2 silicon gaskets/rings in a lid, liquids run out when pouring.An extra ring was included, now I need 2 more silicon rings to refit the other two lids. The seller should furnish those to me without charge! The problem could be that the lids have not been designed deep enough to prevent leakage when screwed on a Ball or Mason glass jar. I will have to return the 3 lids unless seller sends extra silicon rings.

Missing parts don't get many stars. Three lids, two gaskets. Not worth the effort to return, particularly as they're needed. Appear to work without the gasket, but, still, it's not rocket science to put all the pieces in the box.

I think this may be my first 1 star review. It should be zero. Just got these & they leak terrible! It’s also nearly impossible to put them on level. It’s almost like they’re made for another type of jar, not Ball regular mouth jars. I thought I finally got one level & tight but it still leaked. When I took it off, there was liquid under the silicon ring even though I seated it in the groove very well.I’ll try 2 silicon rings inside one lid but I don’t have high hopes for using these. I don’t want to spend 30 frustrated minutes getting the perfect fit on the perfect jar every time I wash it. And even if it works I’ll only have one, since extra rings aren’t included.

I already have two of these for wide mouth jars and use them all of the time. Really. Everyday. When I saw these for a regular mouth sized jar I knew I would have many uses for them as well. I can use them for olive oil, making it easier to pour from than the big jug I buy it in. I can use one for my homemade chocolate syrup and on and on.

These lids are great and much more cost-effective than their name brand cousins! I make my own coffee creamer from dairy-free milk and it's great to be able to store it in a jar and have easy pouring ability. I'm also anxious to see how these would work for pouring gravy at a family meal. I need to look for these in a wide-mouth jar size as well. A note came with my lids that if I thought the cap was too tight, I should soak them in hot water for several minutes to make them looser and fit better. I have no problem with mine fitting my jars. Get them! You'll find lots of uses for them!

I had to try these lids on 3 or 4 different mason jars before I found one that would screw on straight. I don't think it is this item particularly, perhaps it's more of a difference in the way mason jars are made. Still searching for a second jar that works so I can use them both! The item seems well made and there was no leakage when used it in my RV to hold Half and Half. I would recommend with the qualifier that you might need to try a few jars for a "perfect fit."

These lids arrived just fine, but right off the bat I noticed two of the gaskets were not "in" the lid. When I tried to insert them, they were somewhat larger than the groove, almost stretched. The next issue was trying to thread them properly on my Ball Mason jars. It was a tricky, sensitive process and I deemed all that unnecessary. Amazon return policy is excellent, so back they go.

I make 6 Smoothies in quart glass jars at a time & freeze them for future use. These caps are great for when I put the frozen Smoothie in fridge to thaw overnight & all ready for me to drink from or put a straw through the cap. Highly recommend these mason jar caps.
