Bath Body Work Blue WallFlower Scent Control Plug wafts your favorite, always-on fragrance into any room, just the way you like it. 3 Tips to Safely Enjoy Our Wallflowers! 1.To get started, twist right (clockwise) to uncap the refill and twist left (counter-clockwise) to attach it to the plug. 2.Always keep your plug and fragrance refill upright. (Bonus: our rotating plug lets you use a vertical or horizontal outlet!) 3.Because Wallflowers refills contain fragrance oils that may damage finished surfaces and some plastics, always keep a 12" clearance above your plug to prevent damage to surrounding surfaces.
