At each Lawson store, the rice ball "Twice Delicious Top Prime" series is on sale from August 2nd.

This is because different ingredients are used on the top and inside of the rice ball, so you can enjoy two kinds of flavors at once. In the first installment, three items are available: "Salmon and salmon roe" (195 yen including tax), "Grilled pork and mustard" (175 yen), and "Tamagoyaki and mentaiko" (165 yen including tax).

Salmon and salmon roe are topped with a fillet of pickled Atlantic salmon and a large domestic salmon roe inside. Roasted pork and mustard are made by placing roasted pork with fatty pork on top and spicy mustard with roast pork inside. The tamagoyaki and mentaiko are made by placing the omelet of "iodine egg / light" on the top and putting the spicy mentaiko inside.
