Exellent product and great price.
I purchased these lids when starting to make my own kefir. They are easy to use and work so well I don't need to use a strainer to separate the kefir from the grains. I also like the fact that they come in a package of two lids of different colors so I can tell which is the current batch in process and which is the already processed batch of kefir.

Fits wide mouth mason jars and comes in a 2 pack
I have found these caps are the best when you make your kifer at home. The liquid pours out easily. You undcrew the top cap, take it off and use the strainer to pour the liquid into another bottle. It leaves the Kiefer grains in the bottle and you don’t have any mess to clean up. I’m so glad I ordered these. They are very handy, a lot easier for me to make my own kefir from home and are dishwasher safe.

Perfect lid for making kefir.
I love homemade kefir and this lid works great on wide mouth jars. I love how I can slightly elevate the lid to make the perfect kefir.

Perfect fermentation tool
These are just what I needed for my kefir production. Holes are too small for straining but I love these caps for the fermentation process.

Great vented lids, not good strainers.....
I agree with some of the 1-star reviews. Milk kefir does not flow through the holes, and I have to switch back to what I was trying to get away from - a nylon strainer into a bowl. I gave them 3 stars because they provide a seal for the jar - keeping "things" out while allowing venting. I don't have to use a cloth or towel and a rubber band on the top of my jar while fermenting, which is great. If you are looking for a vented closure for your jar to replace cheesecloth or a towel, then I can recommend these. If you are preparing milk kefir and plan to use these lids primarily as strainers, I do not recommend. I don't have any experience with water kefir so I can't provide any input on how they function with that.

Practical and so very useful!
I purchased these when I began my water kefir journey. They are perfect for straining kefir and save having to use a strainer. I also like the clear plastic cover that can be opened partially for air intake or sealed. These are so practical and useful! I liked the option of purchasing 2 at a time as I had them both in use. They are definitely worth the price.
