BOYNEXTDOOR Hosts Teazle Fansign, Blends K-pop with Branding

What happens when fresh tea meets rising K-pop stars? A sweet, fan-fueled marketing moment. On August 28, Seoul’s hip Apgujeong Rodeo district became ground zero for fandom frenzy as BOYNEXTDOOR—the rookie boy group shaking up the K-pop scene—held a special fansign event in collaboration with iced tea brand Teazle.

Woongjin’s First Idol Collaboration Pays Off

Woongjin Foods, the parent company behind Teazle, announced the event on September 5 as a key part of its ambitious campaign featuring BOYNEXTDOOR as their first celebrity brand ambassadors. The partnership kicked off in April, making the August fansign a culmination of months of tasty synergy.

As part of the campaign, Teazle x BOYNEXTDOOR special edition bottles were released. Each bottle’s inside label carried a unique code that fans could enter online for a shot at attending the exclusive fansign event. Unsurprisingly, tea sales—and hearts—soared.

Inside the Teazle Fansign Experience

The fansign wasn’t your average sit-down handshake session. Held over two hours, the event featured live fan interactions, brand-themed music, and a dose of K-pop glitter. The group’s catchy commercial jingle “MY TEA-hyangjeokgyeok, Teazle” (a playful pun roughly translating to “Targeted by My Tea Fragrance”) played in the background. Advert videos also aired, building deeper fan recognition of the brand.

For many fans, this was a rare chance to meet their idols face-to-face and take home treasured memories signed in marker and sealed in heart-eyed emojis. The blend of emotional fan service with savvy branding made this a win-win for both Teazle and BOYNEXTDOOR.

Driving Brand Loyalty Through Fandom

Woongjin Foods is betting on the power of K-pop fandom to boost product visibility and long-term brand loyalty. A Woongjin spokesperson commented, “This collaboration allows us to showcase the Teazle brand in exciting new ways. We plan to continue fostering warmth and connection between our brand and consumers through fun events like this.”

In a world where Gen Z rarely sees a product without wondering what their favorite idols think of it, this campaign is marketing gold. The event is part of a broader strategy to connect with younger demographics in emotionally resonant and culturally fluent ways.

BOYNEXTDOOR: Rookie Group, Major Impact

Since debuting under KOZ Entertainment (a HYBE subsidiary), BOYNEXTDOOR has been rapidly expanding their reach with funky tunes, DIY charms, and now—brand deals. Their natural charisma and fresh energy made them an ideal choice for a lifestyle tea brand looking to stay cool (and cool-you-down).

For the group, this fansign is more than just a promotional pitstop; it’s another step in building a multi-dimensional career that blends music, fashion, and brand culture into one seamless aesthetic. As their popularity grows, don’t be surprised if you find them on your favorite snack wrapper or beauty product soon.

Fans React: “This Feels So Personal!”

• “Getting into the fansign through a bottle was genius marketing—I stocked my fridge just for a chance,” one fan laughed on Twitter.
• Another wrote, “I loved seeing the boys smile while drinking tea. I’m a Teazle girl now. No other brand exists.”
• Fan cams and signed snapshots quickly flooded social media, turning the event into organic viral content.

What’s Next for Teazle and BOYNEXTDOOR?

With Teazle planning more pop culture-driven campaigns and BOYNEXTDOOR continuing their rise, this team-up seems far from over. Both parties confirmed ongoing cooperation, meaning more limited merch, exclusive content, and possibly more live events are on the horizon.

At a time when fan engagement drives not only album sales but beverage choices, the BOYNEXTDOOR x Teazle fansign becomes a textbook example of how to blend K-pop magic into everyday lifestyle brands.
