Designed with infrequent printers with humble needs in mind, the standard capacity Canon CLI-581M does not have the high yield of its bigger brothers. Although this ink cartridge is not for everyone, if you just need to run off the highest quality print available once in awhile, check out the Canon 2104C001.Filled with enough magenta ChromaLife100 ink to print an estimated 223 pages, the genuine Canon CLI-581M treats your most precious prints with respect. Thanks to the special formulation of the Canon ChromaLife100 ink, prints produced with the 2104C001 ink cartridge last an estimated 30 years when behind glass and a staggering 10 years when fully exposed to air.
