Seongsu July Pop-Ups: A Practical Guide to Roblox, Lost Ark, Hearts2Hearts, and TonyMoly Events

Seongsu July pop-ups are especially active in the second half of July 2026, with game, music, fashion, and beauty events concentrated around Musinsa locations and Yeonmujang-gil. For anyone planning a Seongsu pop-up tour, the key is to separate events that need advance booking from spaces that allow walk-in visits.

The main confirmed July lineup includes Roblox X Musinsa’s ‘My Life with Roblox,’ Lost Ark X Musinsa’s ‘Mokoko Street Pop-up in Seongsu,’ Musinsa’s Hearts2Hearts album collaboration pop-up, and TonyMoly’s 20th-anniversary ‘Uncommon Factory.’ Each has a different operating period, venue setup, and reservation rule, so the most practical approach is to build the route around dates first, then check whether a reservation is required.

Seongsu July Pop-Ups to Put on Your Route

Roblox and Musinsa are opening the experiential pop-up store ‘My Life with Roblox’ from July 26 to August 12, 2026, across Musinsa Mega Store Seongsu and nearby parts of Seongsu-dong. Advance reservations opened on July 10, and the announced program includes booths for popular IPs such as Overkill and Knockout, plus a lucky draw stamp tour.¹ Because this event extends beyond July into August, it can work as either the final stop of a late-July plan or the first stop of an early-August Seongsu visit.

Lost Ark fans have a narrower window. Smilegate’s ‘Mokoko Street Pop-up in Seongsu,’ created with Musinsa, runs from July 22 to July 31, 2026, at Musinsa Store Seongsu in Seongdong-gu, Seoul.² The goods shop requires advance booking through Naver Reservation from 6 p.m. on July 10 to 6 p.m. on July 19, while areas outside the goods shop can be visited without a reservation. The announced on-site content includes 19 product types, DIY content, an Instagram event, and photo zones.²

Musinsa’s Hearts2Hearts collaboration pop-up is tied to the group’s second mini album ‘LemonTang.’ The pop-up at Musinsa Mega Store Seongsu uses different concepts on basement level 1 and the third floor, with the new album, photo cards, and collaboration T-shirts available to experience on site. Official MD products were offered for reservation sale through Musinsa’s online store from July 2 to July 12, 2026.³ A Musinsa representative described the project as “an example of expanding music and character IP into fashion, space, and online store experiences.”³

TonyMoly’s ‘Uncommon Factory’ offers a beauty-focused stop on the July route. The 20th-anniversary pop-up runs from July 17 to July 26, 2026, at 99 Yeonmujang-gil in Seongsu-dong, Seoul. The brand is presenting its 20-year heritage, representative products, and new brand message through experiential content, while also pre-launching four Nude Prism Edition shades of ‘Get It Tint Waterful Syrup.’ Advance reservations opened through Naver Place at 10 a.m. on July 10, and on-site visits are also available.⁴

How to Plan a Seongsu Pop-Up Tour in Late July

Start with the dates that overlap. July 22 to July 26 is the densest confirmed stretch among the listed events: Lost Ark is open, TonyMoly is still running, and the Roblox pop-up begins on July 26. If you want to prioritize game-related pop-ups, July 26 is the key date because it is the only confirmed date in this source set when Lost Ark, TonyMoly, and Roblox all appear on the calendar together. If your main interest is Lost Ark merchandise, the more important deadline is July 19 at 6 p.m., when goods shop advance booking closes.²

For Musinsa-linked events, check the exact store name before moving between stops. Roblox is centered on Musinsa Mega Store Seongsu and nearby Seongsu-dong locations, while Lost Ark is listed for Musinsa Store Seongsu. Hearts2Hearts is also at Musinsa Mega Store Seongsu, with separate concepts on B1 and the third floor.¹²³ The source material does not provide walking times between these locations, so visitors should confirm addresses in a map app before setting a tight schedule.

Reservations should be handled event by event. Lost Ark’s goods shop uses Naver Reservation and has a defined booking window. TonyMoly’s ‘Uncommon Factory’ opened reservations through Naver Place but also allows on-site visits. Roblox advance reservations opened on July 10, but the source does not specify the reservation platform in the provided material.¹²⁴ For Hearts2Hearts, the source confirms online reservation sales for official MD products from July 2 to July 12, but it does not state a general pop-up admission reservation rule.³

Visitor Notes: Waiting, Purchases, and Rights

Seongsu pop-ups are not just local brand events; they have become a tourism route for international visitors. The Korea Economic Daily reported that, based on Sweetspot data, cumulative foreign visitor pop-up waiting cases exceeded 12,000 during the 15 months after April 2025, and one in seven waiting cases involved a foreign visitor.⁵ One interviewee, Kathleen, summed up the trend by saying, “Pop-ups are a must-course in a Korea trip.”⁵

That popularity makes basic visit planning more important. Bring the account or app used for any reservation, check whether goods purchase areas are separate from free-entry zones, and confirm refund or exchange notices at the venue before buying. Newsis reported that Seoul City and the Green Consumer Network surveyed 24 pop-up stores in Seongsu-dong and The Hyundai Seoul, finding shortcomings at many stores in areas such as consent for personal information collection, portrait rights notices, and exchange or refund rule disclosure.⁶
