Features:
These sourdough jar covers are designed to replace single-use wraps for your fermentation needs. Made from breathable cotton fabric, they create an ideal environment for sourdough starter, kombucha, kefir, and other ferments by allowing air circulation while blocking dust and insects.
The elastic edge fits securely on jars with 3-4 inch diameter mouths, including wide mouth mason jars and quart containers. This snug fit keeps the cover in place during fermentation and proofing, reducing the risk of contamination.
Each pack contains 4 reusable cloth lids and 2 sheets of brown stickers for labeling. The unbleached cotton material is free from dyes and additives, providing a safe and natural space for your ferments. These covers are machine washable and maintain their elasticity after repeated use.
