Come home to an inviting combination of personal style and continuous fragrance. Just insert this fragrance refill into a decorative ScentPlug Fragrance Diffuser, plug it in, and you'll enjoy room-filling fragrance for up to 30 days. To use, simply remove the refill's cap and slide the bottle into the ScentPlug Base until it snaps into place. Rotate the base's plug to match your outlet, keeping the ScentPlug Fragrance Refill upright. When the oil disappears, it's time to replace.
