This is a spare spool from Studio Ocean Mark. It's used, but there's no blue rust or scratches on the spool edge, and it's generally in good condition. It seems to be a suitable size for 2506 models like the Exist. I think this is a rare item that doesn't come up for sale often. The design is perfect for old-school reels. How about it for those who were looking for one? Rare item, first come, first served! 2508
