We only use the highest quality materials. A combination of medical-grade plastic and extra-strong neodymium magnets make for a durable and incredibly effective nasal dilator. Our Tabs are made of 100% medical-grade, latex-free, hypoallergenic materials. Our proprietary layering achieves a sweat-wicking, incredibly sticky, stay-all-day and night effect. Inside of each Tab is a domed steel disc that the magnets inside the Band attract to.
