Epson printer and Epson ink equals a reliable system.
Size: Standard Capacity, Style: Ink
These Epson Ink cartridges always work. I understand that aftermarket cartridges are cheaper but in the past after using them my printer overtime will fail and ill need to purchase a new printer. I have only used these Epson 822 cartridges in my most recent printer and it has lasted the longest.
