Product details:

Apple weds high-res 4K visuals into its sleek 5mm thin 21.5 iMac with Retina 4K Display. With a 4096 x 2304 native resolution, this iMac provides 9.4 million pixels, which is 4.5 times more than the Full HD 1080p 21.5 iMac. The Retina 4K display also features a wider color gamut. Using a P3-based color gamut, the Retina 4K display provides a 25% larger color space than standard sRGB displays. And with more available colors, the images will appear more vivid and reveal greater detail. The refurbishing process includes functionality testing, basic cleaning, inspection, and repackaging.
