Reckitt Benckiser has ­invested £2.5m in a new Christmas marketing campaign for its limited-edition range of festive Air Wick products.

The campaign, which ­includes TV, will run from the autumn as the new air freshener products hit shelves.

Among the new Air Wick products is the new Ribbons Scent Candles (rsp: £5.99), which contain layers of wax that release fragrance when they melt.

It is also launching Mulled Wine & Crackling Fire and Soft Cashmere & Vanilla fragrances across its entire range of air freshener formats.
