this 350 ml Epson matte black ink tank is new in the box it is designed to work with Epson Stylus Pro 7700, 7890, 7900, 9700, 9890, and 9900. this was kept in an environment with multiple Epson and Canon color white formats in a plate proofing environment for oversized plate proofs. however the 350 ml size was deemed to be needed to be replaced too often and thus it has set on the shelf for quite some time. it will be priced to move for that reason
