Kasukabe City's craft beer shop UNLOCK Brew BASE announced on Instagram a first-anniversary project linked with 54BAL, which opened on the same day. The project is called the "1st.Anniversary Stamp Rally." It is a system where you hop between the two shops to collect stamp cards and limited stickers, and if you complete both shops' stickers, they form "54LOCK."

UNLOCK Brew BASE is a craft beer shop in the east exit area of Kasukabe Station and opened in April 2025. In its introduction at opening, it was said to have a full-scale brewing space inside the shop and to be looking ahead to starting brewing in the attached workshop in the future. As a new craft beer spot in Kasukabe, it is gradually becoming established among local drinkers.

The details shown in this announcement are as follows.

- Stamp card distribution at UNLOCK Brew BASE: April 17 to April 19
- Stamp card distribution at 54BAL: April 17 to April 20
- Sticker exchange deadline: July 18
- Limited stickers: 100 for each shop

On the food side, 54BAL is announcing pasta snacks in garlic consommé and cinnamon sugar flavors. In addition, the windmill-pork shoulder loin carbonara made with UNLOCK's "Hana yori Anko" is available only at 54BAL. Centered on beer, it is designed so guests can move between the shops while also enjoying snacks and dishes, creating a program that celebrates the first-anniversary milestone in a way that suits both shops.
