Transform your mason jars into your new favorite spice jars. Our spice lid is made from sturdy and long-lasting stainless steel, specially designed to bring even more uses to your regular mouth mason jars (jar not included). We recommend using a 4, 8 or 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 feature two different options, allowing you to either shake or pour spices. Because, let's be honest, everything's better in a mason jar.
