Customers love our long-lasting Reed Diffuser Base and its outstanding scent throw! Consisting of a high-performance liquid wicking solution that contains no alcohol or DPG, the solvents were selected to boost any added fragrance's character. By all accounts, this base is superior to any other base tested! Because of how long-lasting and effective the base works with the reeds, less fragrance goes a much longer way, making it more cost-effective than other bases. VOC Compliant. Leaping Bunny Certified.
