100-day warranty, 49mm size filters. Comes with case. All filters are Like-New with no scratches. See photos for more details.
Close‐up filters are essentially positive diopter lenses that screw onto the front of your main lens. They reduce the minimum focusing distance (so you can get closer and fill the frame with small subjects) but do not actually change the magnification of the lens itself in the same way a true macro lens would.
