열쇠 아이콘

Square icon-design presentation featuring a cohesive set of six key symbols on a clean warm-gray canvas. Include a classic brass skeleton key, a modern silver house key, a rounded digital access key, a small padlock-and-key combination, a minimal line icon, and a softly rendered 3D app icon. Arrange them in a precise two-by-three grid with consistent scale, generous spacing, subtle shadows, and clearly differentiated silhouettes. Front-facing product illustration, polished metal materials, restrained navy and gold accents, no labels, no brand marks, no watermark.
