Transform your jars into your new favorite money saver! Our Blue Piggy Bank 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). This bright blue lid features a cute coin slot that doubles as the pig's mouth, and it's hungry for coins! We recommend using a 16 oz. jar for best use. To use, apply some force to snap lid on. Cover, save, cuddle! Because, let's be honest, everything's better in a mason jar. #RaisingTheJar
