The Kubrow Egg is a medium-sized, organic object with a smooth, slightly translucent surface that hints at the lifeform developing inside. Its shape is oval with a subtle asymmetry, resembling a large, exotic bird egg but with a more robust and durable appearance. The shell has a faint, intricate pattern of veins or cracks that glow softly, suggesting a bioluminescent quality, and the color palette ranges from deep blues to purples, with the glow adding a vibrant contrast.
