Polinky is a snack snack with a mesh-like triangle shape, a crispy texture, and a slight sweetness of corn dough. The adult three-star porin key is an "adult-oriented" series developed as "a porin key that we would like to recommend with ★★★ (three stars) so that even adults with a tongue can be satisfied."
The cheese-scented grilled cheese tart flavor, which will be released as the second in the series, is said to be able to enjoy a "deep, high-quality taste" with the richness and flavor of a blended cheese that is not too sweet. In addition, this time, a new texture of dough is used to express the "crispy feeling" of the fragrant tart and the melting of cheese that melts in the mouth.
