Sony PlayStation 2 Multitap

Selling a multitap for the PS2 slim model consoles. Bought a playstation 2 bundle from someone and it came with this but it doesn't fit my Fat model PS2 which is why I am selling it. I didn't know there was a difference in connectors and I thought the plastic piece was there by mistake so I tried to chisel it away. That's the only cosmetic defect otherwise it should still connect and function properly. Looking to sell it or trade it for the fat model multitap it the buyer has one to trade. Pick up or meet up locally only.
