Keep the bugs out but let the air in with these 100% unbleached cotton jar covers. Perfect for fermenting kombucha, making yogurt, brewing sun tea, pickling veggies, or storing dry goods. Each set includes 5 durable, tightly woven covers (8.5x8.5 inches) that fit jar openings from 2 to 6 inches. You also get 6 rubber bands (one extra!) and about 3 meters of colorful cotton rope to secure the cloths neatly. They’re food-safe, reusable, and easy to clean – just toss them in the washing machine. The natural fabric allows airflow while keeping dust and insects away. Great for DIY kitchen projects, pantry organization, or even as cute rustic decor for parties. They make thoughtful gifts for home cooks, canning enthusiasts, or anyone into sustainable living. Ditch the plastic lids and go breathable – your ferments will thank you.
