Seongsu CU RIIZE Pop-Up: Little RIIZE Goods, Dessert Collabs, and Fan Events

CU’s Seongsu RIIZE pop-up is turning a convenience store dessert stop into a K-pop fan destination. Running from June 20 to July 5, 2026, the CU X RIIZE pop-up is being held at CU Seongsu Dessert Park, located at 21 Yeonmujang 3-gil, Seongdong-gu, Seoul, with Little RIIZE collaboration products and on-site events announced through CU’s official social account. ¹

The timing is easy to understand: Seongsu has already become a popular neighborhood for pop-ups, desserts, and fan-driven culture, and this event brings all three together inside a CU store. For anyone following Seongsu Dessert Alley or planning a fan-focused stop in the area, the pop-up gives the neighborhood’s dessert scene a very specific K-pop angle.

What the Seongsu CU RIIZE Pop-Up Offers

The collaboration centers on Little RIIZE, the character IP connected to RIIZE. BGF Retail announced that CU would sequentially release six collaboration products using the Little RIIZE IP: three breads, two macarons, and one bottle candy. ² Newsis also reported the same six-item structure, describing the lineup as breads, macarons, and candy released in stages. ³

The pop-up at CU Seongsu Dessert Park is designed as more than a shelf display. Source summaries describe a message zone and a limited-goods giveaway event, while other reporting notes that the store is decorated with RIIZE member sheets and a message space. ^{2 4} That makes the event closer to a small fan experience than a typical convenience-store product launch.

The collectible element is also central. Electronic Times reported that the collaboration products were introduced to mark RIIZE’s second mini album, “II,” and that each bread includes one random sticker from 54 types, while each macaron includes one random epoxy sticker from 12 types. The bottle candy is scheduled for release on July 8, 2026. ⁵

That random-inclusion format matters because it gives fans a reason to compare, trade, and return. Kyunghyang Shinmun reported on fans exchanging stickers from RIIZE collaboration bread at CU Seongsu Dessert Park on June 21, one day after the pop-up opened. ⁶ In other words, the collectible design is not just a product detail; it is part of the pop-up’s social energy.

Why a Convenience Store Became a Fan Stop

The setting is part of the story. CU Seongsu Dessert Park is not being treated only as a place to buy snacks; during the pop-up period, it functions as a compact meeting point for dessert shoppers, RIIZE fans, and visitors curious about Korean convenience-store culture.

Kyunghyang Shinmun reported that the store’s foreign customer sales share exceeds 30%, tying the pop-up to a broader pattern of overseas visitors seeking out Korean convenience stores in Seongsu. ⁶ A CU representative was quoted as saying, “Korean convenience store culture itself can be seen as having become a new tourism item.” ⁶ The quote helps explain why a convenience-store pop-up can feel travel-relevant, not just retail-relevant.

BGF Retail’s own positioning also connects convenience stores with K-pop fandom. Park Hee-jin, head of BGF Retail’s strategic MD team, was quoted as saying that “convenience stores and K-pop are creating synergy with each other and offering consumers a differentiated experience.” ⁴ That is a straightforward summary of the strategy behind this kind of collaboration: familiar daily retail plus fan culture, packaged into a limited-time visit.

For readers planning around Seongsu Dessert Alley, this is also a reminder that the area’s dessert appeal is not limited to independent cafes. In this case, CU’s dessert-focused store becomes part of the same walking circuit, especially for fans who want a K-pop collectible stop alongside sweets.

Dates, Location, and Product Timing to Know

The key pop-up dates are June 20 to July 5, 2026. The official CU social notice lists the venue as CU Seongsu Dessert Park at 21 Yeonmujang 3-gil, Seongdong-gu, Seoul. ¹ Since the current date is June 25, 2026, the pop-up is already underway and still has scheduled operating days remaining.

The product rollout began before the pop-up. Edaily reported that CU would begin sequentially releasing the Little RIIZE IP-based collaboration products from June 17, 2026. ⁴ The pop-up then opened on June 20, giving fans a dedicated Seongsu location for the collaboration experience.

One detail to keep in mind is that not every item has the same timing. The bottle candy is scheduled for July 8, 2026, which is after the pop-up’s listed July 5 end date. ⁵ The sources available do not state that the bottle candy will be sold at the pop-up during its run, so it is safest to treat July 8 as a separate product-release date.
