Popular idols teaming up with companies to drop collaboration products are making waves — and fans are buying fast.
On the 11th, Korean beauty tech company APR’s brand MediCube announced via its official Japan social media that it is launching a hairbrush.
The product was unveiled with IVE’s Jang Wonyoung and sports a cute look that instantly recalls her much-buzzed-about trademark filing for ‘Forever:Cherry’.
The item is currently on sale through Qoo10 Japan, priced at 3,600 yen (about 34,290 KRW). Once specs and pricing went live, netizens reacted positively: “At this price, it stacks up well against others,” “It’s practical and super cute.”
It hasn’t launched in Korea yet, but domestic fans are expected to get their hands on it soon. On the 21st, Forever:Cherry’s official Instagram amped up anticipation with a post hinting at upcoming colors. The poll featured sky blue, deep purple, and red, plus an eye-catching option that blends light purple with pink.
Meanwhile, BTS’s Jungkook joined forces with Calvin Klein (CK) to drop ‘CKJK’ — and the response was explosive.
On the 18th (local time), Calvin Klein announced on its official social media the first-ever collaboration collection ‘CKJK’ designed directly by Jungkook. It’s the first time in Calvin Klein’s 58-year history that an idol has taken part in the design process, drawing major attention.
Reports say Jungkook was hands-on from early concept talks to the final design details — weighing in on denim washes and even tweaking the fit of the brand’s signature jackets.
Proof of his impact came fast: on the 20th, all 36 items in the ‘2026 CKJK’ collection sold through the global official site, with the U.S. store selling out every piece in under 30 minutes. Japan, Poland, Australia, Italy, and other major markets also recorded full sell-outs.
As idol–brand collaborations ramp up, the very idea of ‘merch’ is rapidly expanding.
It’s a win-win for companies and artists — and for fans eager to collect more diverse, high-quality goods.
