Pour and Drink from Your Mason Jar Put your Mason jars to work and eliminate single-use water bottles and containers. This pour lid fits standard wide-mouth jars and is made of a no-break plastic, so it will last use after use. Choose a single lid or buy in a pack of 4. Each lid comes with a silicone gasket (you supply jars). Flip-top design makes pouring and sipping from jars easy and neat. Use as a reusable water bottle or drink container, homemade salad dressing dispenser, storage containers for your pantry, bathroom or office, even as fermentation container (when you add an airlock - you supply). Fold-out carry loop allows you to easily take your jar with you. Fits wide mouth, standard-sized Mason jars, including Atlas, Ball, Bernardin, Golden Harvest, Kerr, Kilner, Legacy, Orchard Road and Quattro Stagioni. Eco-friendly, reusable and durable! Lab-certified, Food-safe, BPA-free plastic. Removable silicone gasket for a leak-proof seal and easy-to-remove lid. Stain resistant and freezer proof. Top-rack dishwasher safe.
