This is an Excellent 58mm Hoya Skylight 1B Filter with Case.  The case shows wear but has protected the filter well.  I would almost say the filter is near mint condition.  The glass is clean and clear but will be inspected and cleaned again if need be, prior to packing and shipping, so you receive the best possible filter described above.  I strive to provide the best products, descriptions and service so you can buy with confidence.  I know how I hate receiving items un-cleaned or not as described, so I try to avoid any disappointments on your end by giving you as many details as possible so you make an informed purchase!
