AXL Fermenting Wide Mouth Vacuum Lids for Mason Jars, Airtight, Airlock, Leak-Proof Seal and Innovative Jar Lid, Food-Grade Plastic Storage Caps for Mason, Kitchen (4 Pack Lids & 1 Air Extractor Pump)

I have tried a few other kits here on Amazon. By far this one is the best. Good quality lids, wide seals and good snug fit. I also enjoy that these are stackable. Seller has great communication I had a problem with one of my lids,he immediately sent me two. So far everything seems to be working properly. No leaks! Only suggestion would be making the air pump available for purchade separately. In case you need another.

I juice celery and a smoothie in the evening, for the next morning. This is a slick way to keep them fresh. I love it!

Very nice quality and sturdy. Everything last longer when you take out the air. Only reason I give it 4 stars is that it started loosing the suction after it’s in the fridge for a day. Not sure why it started do that. Maybe I’m doing something wrong

Oh My Gosh I absolutely lurve these lids and the pump, I was surprised how small the pump actually is which is great because it fits inside my kitchen draws so easily. I love that I don't have to plug anything in to use it.I wanted to see what these were like before ordering anymore but now I have no hesitation in ordering again, in fact I am about to place another order with this Seller.Thank you for such a Fantastic Product!!!Sydney, Australia
