Sniff, lick, sign, seal and deliver with new chocolate stamp

THE Easter Bunny has teamed up with a Belgian post office in a bid to create the world's first taste and smell stamp.

The post office released 538,000 stamps on Monday that have pictures of chocolate on the front but the essence of cacao oil in the glue at the back for taste and in the ink for smell.

One stamp collector Marie-Claire Verstichel said while the taste was a bit disappointing, "they smell good".

Easter is the season for chocolate in Belgium, with Easter eggs and bunnies all over supermarkets and speciality stores. Now, they have stamps to match.

A set of five stamps costs 6.20 euros ($A7.75) but might leave a customer hungry for more.

While tasty stamps are a fresh postal twist, stamps with special odors aren't new.

In 2009 Britain produced a full set of scratch and sniff postage stamps with the scent of eucalyptus.

And in 2010 Germany created four scented stamps for charity, perfumed with the scents of lemon, strawberry, blueberry and apple.
