These glass weights are designed to help keep ingredients fully submerged during fermentation. Made for wide-mouth mason jars, each weight features an easy-grip handle that allows simple placement and removal. The smooth glass surface helps maintain cleanliness and supports an even fit inside the jar. Ideal for fermenting vegetables, pickles, and similar preparations, the weights sit firmly to help maintain proper coverage. Their clear design makes it easy to see the contents while keeping the process organized. With nine pieces in one set, they offer convenience for multiple jars or batches.
