Now this is cunning! A strange name but a unique product. You buy a box of beautifully packed 3 rubber strips, perfumed to suit, and tuck each strip behind cushions; between your garments; in the linen cupboard or where you will. Will even scent your car! The scent will continue to diffuse once unwrapped for about 8-9 months. Protected in its re-sealable foil envelope it will last for years: easy and safe – no oils to stain; no electricity, wiring, flame or batteries. Unique – like everything from Malle.
