Australia Post has released a scratch and sniff stamp featuring a rose for Valentine’s Day cards and letters.

The stamp bears the image of a classic red rose in full bloom, and when scratched it gives off a sweet rose scent.

Australia Post spokesman Noel Leahy said the stamp was a sensory explosion "sure to rekindle warm feelings for every romantic out there".

Mr Leahy said he hoped the initiative would encourage lovebirds to shy away from sending a less romantic email or SMS on February 14 this year.

"Sending an SMS or email doesn’t have the same impact as a card you choose personally and accompany with a hand-written message of love," he said in a statement.

"The value of a heartfelt love letter and scented stamp is priceless."
