I have four hi-capacity black ink cartridges for Epson C64/C84/CX6400 printers. I bought these wholesale for my CX4600 but the high capacity ink cartridge does not fit into the CX4600. They replace the Epson T043120 ($32.99 retail) and are generic non branded cartridges. I just bought one low-capacity Epson cartridge for $25 so retail on the hicap generics is probably around $75.

I'm asking $40 obo shipped to the conti US....
