The sheet displayed above is been issued by Australia on 27th January 2006. The specialty about the stamps are that it contains the fragrance of the Rose Flower embedded in it. The technology behind this is micro-encapsulation. In this process tiny particles or droplets are surrounded by a coating to give small capsules with many useful properties. A non-fragrant stamp also was issued along with this with its denomination being in solid grey colour.
To release the scent of rose one has to rub his finger accross the stamps.
