With their unique, wax-free design, Spheres elevate any room with beautiful, lasting fragrance and effervescent charm. There’s never any hot mess to clean up, plus each Sphere lasts more than 2X longer than wax melts. All you need is 2-4 Spheres and a ceramic, metal or glass bowl. For an even more intense aromatic experience, simply place 1-3 Spheres on a warmer and savor the scent to your heart’s content.
