Masontops 8 PC Pickle Pebbles Glass Weight & Pickle Pipes Airlock Kits - Small Regular Mouth Lid for Pickling & Canning

Nice and heavy, not too thick. The little protrusion at the top makes it easy to grab and pull the weight out of jars.

Great product in fermenting vegetables.

Works.

I'm fairly new to fermenting (and easily distracted) so I needed something easy. So far I've made a fermented hot pepper sauce, onions, and garlic. The pepper sauce turned out amazingly well, and I just tried the onions today - so good!I had no trouble with the pipes and the pebbles are wonderful (although very small pieces can still work their way up to the surface).The only thing I'm not crazy about is the pipes take on the odor of whatever you ferment. I know that's just the nature of silicone, but if you plan to ferment fruits, either keep a pipe or two just for those or have a second set. I definitely don't want fermented berries tasting like garlic!I plan to purchase the wide mouth set at some point, too.

The pickle pipes don't prevent mold nearly as well as they say they do, and if your ferment does get mold growing it's impossible to get these things totally clean. About half of my ferments have molded when using these and I can't get the stains out of them no matter what I try.The glass weights are great as long as you are absolutely stuffing your jars - if the contents shrink a bit while fermenting, the weight can slide down along the side and allow the contents to float.
