Of the 3 kinds of plastic lids I’ve bought, these are the best!! They seal waterproof with silicone ring in lid. You can also easily remove the seal to clean. The design of the lids is the best handhold, you can get a good grip on the lids and apply pressure easily. The plastic is thick and substantial. I’ve bought other much cheaper ones and they are a pain.

You know the trend where people are now interior decorating their fridge? They add pictures, and flowers, and tchotchkes to make it cute. Well I definitely don't do that. But I did buy these super cute lids that brighten my day. The grip is fine, some may even say stellar. And the seal is *chef's kiss* divine. There's a time and place for ol' faithful's ring and reused seal tops with some half faded permanent marker that say "dill pickles" or "rhubarb jam", but I like these a lot better.

I’ve had these for a while now. The caps have worked well. They clean up easily win the dishwasher. They seal on the jars very well with no leakage. Unlike the metal caps, they don’t rust. Metal ones may be great for one use canning, but for repetitive use to store short term items, these have been excellent. I like the plastic lids allowing for easy marking with a wax pencil (dates for example). I can recommend these for anyone considering purchase.

The lids are great! I had to edit my review as I had lids mixed up as I’d ordered others. These have a built in seal/gasket. They do not leak and They are working great. No more metal lids for storage. Using now on my refrigerated homemade pickle jars!

I like the colors. Works better for use outside canning than the canning lids.

Bought these to use when making fire cider b/c the vinegar corrodes the metal lids. The shape makes them easy to grip when removing which is always helpful. I also especially like the built-in seal. At $15, these are a bit on the pricey side; however, in comparison to the cheaper ones I found, these are much nicer quality for sure.

These are great lids for wide mouth Mason jars. They won't rust like the traditional, they can go in the dishwasher and they close tightly. The grip design also make them easy to open.
