As the world released scented stamps, UK went a step ahead and issued Scratch and Sniff Stamps. To commemorate two Nobel Prizes, UK issued two distinct stamps.

To commemorate 100th Anniversary of Nobel Prize given to Physiology or Medicine UK released a stamp depicting green cross. The stamp releases Eucalyptus scent when scratched and sniffed.

On the other hand, UK also issued another such peculiar stamp. This stamp celebrates Chemistry prize and depicts a Carbon 60 molecule. The stamp is heat sensitive, and firm pressure from a fingertip reveals an ion hidden behind the black on white design.
