Katseye's debut EP, SIS (Soft Is Strong), is the 2024 debut EP from one of K-pop's most anticipated global girl groups. The title carries a double meaning: a declaration of the group's core philosophy that softness is its own form of strength, and a tribute to the sisterhood built across six cultures and three continents. This Vintage Bottle pressing includes 6 photocards, one featuring each member: DANIELA (USA), LARA (USA), MANON (Switzerland), MEGAN (USA), SOPHIA (Philippines), and YOONCHAE (South Korea).
For music historians and pop investors, owning a pristine, uncirculated copy of a major group's debut release is the ultimate play. It’s capturing the "Genesis moment" of their legacy before they scale to massive stadium status.
