FS or trade Filters socks

[Frizz]

I have 8 unused Innovative Marine, 200 micron filter socks that are 7" openings. they have never been used. I ordered the wrong size but I didnt send them back soon enough.
Would like to sell all for $50.00 or trade for comparable/ washable 4" filter socks or maybe even livestock. Central Phoenix.
