This product is a smartphone case with 8 pieces of "miniature sushi" that is small enough to fit on your finger. There are eight types of sushi ingredients: tuna, octopus, horse mackerel, shrimp, sea urchin, salmon roe, conger eel, and egg. In addition, it even has a "gari" that looks just like the real thing.
