Mos Burger sells the "Summer Lucky Bag" every year. Following the great popularity of the Tamagotchi-themed freebies included with the Mos Wai Wai Set last spring, this year's collaboration for the Summer Lucky Bag has been realized. Tamagotchi will celebrate its 30th anniversary this November. In recent years, it has gained popularity among a wide range of age groups, not only young children but also the parent generation who once played with Tamagotchi. The design is a special, cute, and lively original illustration that incorporates the world of "Tamagotchi Paradise," which was released last summer and became a major topic, along with Mos Burger products. It will be provided in a special bag with original designs, along with "meal vouchers (approx. 5,000 yen worth, consisting of 10 vouchers of 500 yen each).
