The image shows a set of four black and blue connectors arranged in a horizontal line on a white surface. The connectors appear to be made of plastic and have a cylindrical shape with rounded edges. They are arranged in two rows of three, with the top row slightly overlapping the bottom row. Each connector has a small hole in the center, which could be used to connect two or more connectors together. The blue connectors have a textured surface, likely for better grip and stability.
