To satisfy the demand for higher-volume printing on portable printers, this RP-108 Kit includes enough ink and paper to print 108 postcard-size photos (4" x 6") in the Canon SELPHY CP1200, CP1300, CP820, CP910; PCC-CP400 and PCP-CP400. The RP Series offers higher capacity ink cassettes so you can spend your time printing instead of changing ink. Once printed, the photos are instantly dry, smudge-free and water-resistant.
