Our Everlast continuous ink bottles are designed specifically for use with the Epson C88 inkJet printers. Continuous ink systems offer tremendous savings as a CIS is 10 times less expensive than using cartridges. The system works by the print head drawing ink from bottles next to the printer. Currently, we are only stocking the refill ink bottles. For information on the CIS system, please give us a call at 1-800-562-7760.
