Our wax melts are made with premium fragrance oils that are paraben & phthalate-free & USA Grown Soybeans. Please see picture for scent descriptions. Contact us if you don't see a fragrance you'd love, we might just have it with over 400 different scents in stock! Custom Labels avail too! Each Melt is 3oz. & has Six .5oz break-off cubes. Burn time (approximate) - 60 - 70 hours of warming time. Hotter warmers will run a more intense scent for a shorter period of time, cooler warmers will run a less intense scent for a longer amount of time. We recommend warming 2 cubes for 3-4 hours at a time over multiple uses until the scent is gone from the soy wax. Prolonged warming (more than 3-4 hours) will use the scent faster but is safe if prolonged warming is desired. When you're ready to change scents, carefully soak the melted wax up with paper towels & toss it in the trash or save it for use as a fire starter. Be sure to wipe residual wax from the warmer before adding new scent cubes.
