BTS's official Version 4 lightsticks, which sold out quickly after the group launched an ARIRANG merchandise line with Target following their album release on 20 March, remain available through resale and third-party retailers. The lightsticks became one of the most sought-after items in the collection, reflecting the wider surge in demand for BTS merchandise and K-pop lightsticks more broadly, giving fans a chance to secure one ahead of the band's remaining 2026 ARIRANG tour dates.

Although Target's stock of the lightstick, originally priced at $69, has sold out, fans can still buy it via StockX and Amazon, where prices have risen due to demand—$66 on StockX and over $80 on Amazon. Lightsticks are light-up wands unique to each K-pop act, used by fans to show support at concerts; BTS's version, known as the ARMY Bomb, features a distinctive clear bomb-shaped head bearing the group's logo. The article notes that official lightsticks have historically been difficult for fans outside South Korea to obtain, though rising demand is prompting more US retailers to stock lightsticks for acts including Stray Kids, ATEEZ, TWICE and aespa.
