Test Tubes Shop Icon Revised Preview

Generated from: Revised pixel art game building icon, exactly 48x48 pixels, no larger image. Cookie Clicker style flat cartoon building icon: two laboratory test tubes standing side by side at slightly different depths, with a shorter third tube layered behind them, flat chunky shapes, thick bold black outlines, playful clean cartoon look. The tubes are drawn in black and white only (white tube bodies with black outlines) but with visible depth: soft shading and darker gray gradients on the tube bodies, bright white highlights and glass reflections along the edges, liquid levels with darker gray fill inside the tubes, and a subtle dark shadow underneath the tubes. Solid dark blue-gray background (darker tone from the project palette, color #363d52), with a subtle vertical gradient darkening toward the bottom. A thick black outline border runs around the entire edge of the icon. Centered composition, subject fills most of the frame. Crisp 48x48 pixel art, single icon, no text, no letters, no watermark.
