uni pin fine line pen light grey Size:0.1 This sticker pack contains 50The Uni Pin Fine Line Light Grey lays down a soft, cool grey rather than a strong dark tone, suited to faint shading, base sketch contours, or subtle drop shadows behind darker title text where a full black or dark grey line would feel too heavy.
