Our plug ins come in our full fragrance room to keep gently scenting your home. Each plug in units comes with one scent bottle. Maybe purchase some refill bottles so you can change your homes background scent whenever you fancy. We have tried quite a few gingerbread fragrances over the years, but have never really found one that we liked enough to stock...until now that is! This fragrance is going to be a firm favourite! It's got the Gingerbread and the spice without being too sickly sweet. A future festive favourite.
