In celebration of the National Guide and Scout Movement, the Swiss postal service has released a commemorative stamp that gives you the aroma of a campfire whenever you scratch it.

Swiss scratch and sniff stamp released to all cantons

To mark the National Jamboree, Swiss Post has released a stamp which smells of campfire smoke. The scent is released by rubbing the coating of the stamp and is designed to garner memories of “campfires, huge campsites and spending time together with friends,” according to a statement by the company.

The 1,10 Swiss franc stamp is now available for purchase in all Swiss cantons. The campfire stamp is the fourth time Swiss Post has used smell to coax its customers, most famously making a “chocolate flavoured” stamp to celebrate the 100th anniversary of Chocosuisse in 2001.

Campfire stamp one of many quirky stamps from Switzerland

In recent years, the state-run company has been experimenting with several different and unusual stamps to increase demand. Some highlights include an embroidered stamp, a stamp made entirely of wood, a stamp in Braille and the world’s first crypto stamp.

The announcement of the campfire stamp came alongside other new items for philatelists to collect. Among them is a tribute to the Swiss national hero William Tell, depicting the folk tale of how Switzerland was founded.
