Sweet and sour stamps
Stamps released in China to celebrate the Year of the Pig taste of sweet and sour pork.
When you scratch the front of the stamps, it smells of the popular chinese dish and when the back of the stamp is licked it tastes of the dish too.
The stamps are on sale in China ahead of their New Year on February 18, reports Metro.
Royal Mail launched Britain's first scratch 'n' sniff stamp in 2001 - they gave off eucalyptus aromas.
