Silver is the color of moonlight and this version of the popular black Noctilux - M 50 coffee mug. Its matte silver finish reflects the style of the new, silver anodized version of the Noctilux - M 50 mm f/0.95 ASPH. lens. Both its look and feel are strongly reminiscent of the lens: special printing in 3-D relief emulates the lens rings. The mug comes complete with a practical silicone cap for the daily coffee to go.
