At each Dom Dom hamburger store, a "lucky bag" will be released on May 1st to commemorate the change to the new era "Reiwa" (excluding some stores). The price is 2,000 yen (tax included).
A "meal discount ticket" (500 yen ticket x 4) that can be used with Dom Dom hamburger and a "Kaigen Memorial Original Mug Cup" with the symbol mark "Domuzo-kun" printed on it are included in the set. The meal discount voucher is valid for July 31, 2019.
Due to the limited quantity, it will end as soon as it runs out. Please check the official website of Dom Dom Hamburger for the stores to sell.
