Transform your mason jars into your new favorite salt and pepper shaker. Our Salt and Pepper Shaker lid is BPA Free and made from recycled materials, especially designed to bring even more uses to your regular mouth mason jars (jar not included). We recommend using a 16 oz. jar for best use. To use, apply some force to snap lid on. When properly secured, this stylish lid will provide you with a tight seal and a unique way to store the two most common seasons. Cover, fill, season! The definition of multi-purpose. Because, let's be honest, everything's better in a mason jar.
