,325 tail grommet
#51 nose grommet
i think these are striper swipers that didn't make the cut for they all have slight imperfections and the belly swivel is cut. They are packaged as " bluefish ".
I thought I read they were some type of foam poured solid. Very cheap less than 10$ if you search the auction sites. Just getting harder to find them. I actually got a couple of the striper swipers cheap and ended up using them without the belly hooks also. Just one of my go to plugs I have used for awhile. They fly great and throw a ton of water. Had to reconfigure the nose loop for ease of use. Remove the tail hook and they work great as an agitator with a trailer. Like the casting eggs.
