Wax melts, commonly shaped as snap bars, are small, fragrant blocks of scented wax that can be melted in wax warmers to release their aroma. Designed for ease of use, snap bars can be broken into pieces, allowing users to mix and match scents or control the intensity of the fragrance. They come in various scents, from fruity to floral and seasonal blends, making them a popular choice for home fragrance enthusiasts looking to enhance their ambiance without the use of an open flame.
