This is a set of genuine knobs that came with the SHIMANO Ocea Jigger 2000NRMG. Includes the knob, cap, 2 screws, 2 bearings, and 4 washers. The washers are extras from when I installed custom knobs. They can also be used on the original knob. I removed these after purchasing the reel new and replaced them with custom knobs, so I'm selling them. They have never been used for fishing, but they are still considered used, so please refrain from purchasing if you are overly concerned about condition. The size is D type. Please check the Shimano website for compatibility.
