Hershey's Kisses is a brand of chocolate first produced by the Hershey Company in 1907. The bite-sized pieces of chocolate have a distinctive conical shape, sometimes described as flat-bottomed teardrops. Hershey's Kisses chocolates are wrapped in squares of lightweight aluminum foil. A narrow strip of paper (called a plume) sticks out from the top of each Hershey's Kiss wrapper. Originally designed as a flag for the "Hershey's" brand, the printed paper plumes were added to the Kisses product wrapper in 1921 in order to distinguish the Hershey's Kiss from its competitors who offered similar products.
