This is a Kenko filter, Zeta plus Protector, 77mm. I purchased this several years ago and have kept it in storage, unused. There are no scratches or scuffs. The original box has some damage and tears. Also, the included lens cloth is missing. According to the manufacturer's description: ZR coating achieves ultra-low reflection. Optimal for the latest high-performance, high-image-quality lenses. By adopting the newly developed ZR coating, ultra-low reflection of 0.3% or less is achieved. This performance rivals the coatings applied to the highest-grade lenses of each manufacturer, making it a recommended lens filter for those who value quality. Slim frame design compatible with ultra-wide-angle lenses. While the glass thickness is a standard 2mm, a high-precision machined aluminum frame is used to make the frame thinner. You can use it with confidence even with ultra-wide-angle lenses.
