These are great little caps for kombucha. The reason I took one star off is that they do break - but that said, so far I have had only one break and it did not cause any problem with the kombucha. They are very well packaged and the kombucha that I make has the perfect amount of carbonation using them. I am not sure how long lived they are as far as using them multiple times. I may come back later with a better update after I have seen how many times they can be re-used. I also do not make kombucha using extra sugar or any flavoring for the second ferment. That may cause more pressure on the caps than I am giving them. Still a newby at the kombucha brewing.

i think that these screw on caps will be just fine and i like how they have the seal-tight tapered liners inside the cap to seal against the glass bottles to keep the contents of your bottles in the bottles.

I had these salad dressing bottles where the lids broke for years and found these bottles caps are way better and fit perfectly 🤗🥰

One broke immediately, but the others were solid.

I had my kids save their glass kombucha bottles to use as juice bottles. All great except the plastic lids started disappearing. Ordered these and they fit perfectly. Also, because they are substantial, no one throws them out by error. They save them with the bottles to wash and reuse.

I’ve had a few break on me as I was tightening down without much force. Maybe the plastic is too brittle? Still ok for the money but not perfect

We were frustrated when cleaning our growlers for an event only to discover several of the lids were rusted or otherwise crappy. Ordered these, they arrived fast and were a perfect fit. Washing was a breeze - pop the clearish plastic out, wash both parts, let it dry and use. No complaints.
