This is achieved by our manufacturers using as many components from the genuine Neopost 4150720R cartridge as possible and then refilling the unit with top quality blue ink.The resulting remanufactured Neopost 301043 franking machine ink cartridge offers the same amount of prints as the original and compatibility with all the same printers including the Neopost IS6000. VAT and UK shipping is included in the price so the goods will be delivered for the price you see here.
