The Cure Black Q Posket figure captures the character in a stylized, chibi-inspired design common to the Q Posket line. The figure stands in a dynamic pose, with her signature long black hair sculpted with a glossy finish and subtle waves. Her outfit is rendered with bold black tones accented by bright pink highlights and gem-like details on the chest and waist. The eyes are oversized and glossy, in classic Q Posket fashion, giving an innocent yet determined expression. The piece is designed with smooth surfaces and a petite torso, balancing cuteness and heroic presence. The base is simple and stable, allowing display on shelves or cases.
