A full-size interactive replica of Rumi’s sain-geom sword from *KPop Demon Hunters* is available to pre-order ahead of its planned 1 July 2027 release. The product is aimed at collectors and cosplayers, reflecting the franchise’s continued commercial success and expanding range of merchandise.

Priced at $224.99, the roughly 40-inch plastic sword includes a purple-tinted display stand and has more than 50 LEDs, motion-activated lighting and film-inspired sound effects. It responds to movement, music and singing, uses a rechargeable battery, and can remain illuminated through USB-C power when displayed; lower-cost Nerf versions are also being promoted while stock lasts.
