This food eraser made by Iwako, is a parody of the Calbee snack food "Sapporo Potato". While the real Calbee product is BBQ flavor or "ba-bikyu" in Japanese , the parody is "munekyu aji",which means the description of the feeling of righting in one´s chest caused by powerful feelings of love. Thus the picture of this sweet potato couple deeply in love.
This eraser is made by Iwako. It comes in the snack eraser assortment. The other food erasers included are , Burnt Octopus, Brat Team Baseball, Chocky, I AM MACHO and Lettuce Child.
