TWICE Flat1399 Pop-up Guide: Dates, Venue, Floors, and Reservation Notes

The TWICE Flat1399 pop-up is officially running as the TWICE WORLD TOUR FINALE in SEOUL POP-UP STORE, a Seoul event tied to the group’s world tour finale. For readers searching for the TWICE Seoul Pop-up, the key details are clear: it takes place at Flat1399 Studio in Seoul from July 2 to July 12, 2026, with shopping, exhibitions, interactive missions, and tour-linked visuals built around TWICE’s official character world.¹

TWICE Flat1399 Pop-up: Essential Visit Facts

The pop-up is being held at Flat1399 Studio in Gangdong-gu, Seoul, and several reports identify it as a commemorative event for TWICE’s Seoul finale concerts for the sixth world tour, ‘THIS IS FOR’. The related concert dates are July 10 to July 12, 2026, at KSPO DOME in Seoul.²

The timing is important for visitors because the pop-up overlaps with the final concert weekend. TenAsia reported that all three Seoul finale performances at KSPO DOME were sold out, so the pop-up may draw both concertgoers and fans visiting Seoul around the same dates.³

The broader tour context also explains why the event is being framed as a finale experience rather than a standard merchandise stop. Yonhap reported, citing JYP Entertainment, that the tour concludes at a scale of 81 total performances across 44 cities, including the finale shows.²

What to Expect Inside Flat1399 Studio

The space is organized around TWICE LOVELYS, the group’s official characters. Newsis reported that the first floor is set up as an MD purchase area, while the second floor is used for exhibition and experience content.¹ This means visitors should treat the pop-up as both a shopping stop and a participation-based fan space, rather than only a goods counter.

The reported visual concept is summer-themed. Sports Kyunghyang described yacht and marine objects, seasonal props, and Seoul encore-related visuals and content as part of the installation.⁴ TenAsia similarly noted the use of official characters, yacht decorations, marine props, and tour visuals to create a summer atmosphere.³

Participation features are also part of the visit. Reported programs include ‘TALK THAT TALK : LYRIC QUIZ’, ‘COLOR YOUR TWICE LOVELYS’, a message wall, and an SNS event. BizEnter reported that these elements are presented as interactive programs, with official Seoul encore concert goods also being sold at the site.⁵

Stamp missions are another practical point to know before visiting. Newsis reported that participants in missions such as random quizzes, character decorating, the message wall, and SNS activities can receive prizes including scratch lottery tickets.¹ The available source material does not specify prize quantities, daily limits, or whether all rewards are available throughout the full operating period, so visitors should check current on-site or platform notices before assuming availability.

For shopping, the sources confirm sales of official MD and Seoul encore concert official goods, but they do not provide a full product list, price list, restock schedule, payment rules, or purchase limits. If those details matter for your visit, the most reliable next step is to verify them through the official reservation or fan platform before going.

Reservation and Planning Notes

A reservation issue was publicly addressed before the pop-up opened. On June 26, 2026, FANS posted a notice stating that a problem during the reservation process had been resolved. The issue affected some users who received reservation completion notifications but could not see the reservation in their booking history, as well as users who were incorrectly blocked from making a new reservation because the system said they already had one.⁶

FANS stated that the issue had been fully resolved and instructed affected users to try making a reservation again.⁶ If a visitor was affected by that earlier error, the source-backed action is simple: retry the reservation process through FANS rather than assuming the previous failed or invisible booking is still valid.

For planning, the confirmed operating window is limited to July 2 through July 12, 2026. The available source material does not provide daily opening hours, entry time slots, walk-in availability, refund rules, or detailed reservation conditions. Because the pop-up is connected to sold-out finale concerts and a limited event period, visitors should verify entry requirements and current availability before traveling to Flat1399 Studio.
