Tried remanufactured and off brand cartridges and kept running into compatability issues with my Epson Work Force Pro WF-3820. These are more expensive-but they work. Have to take into consideration the fact that my printer is used for business and down time because my new cartridges aren't recognized by the printer costs $$$

Authentic

Style: Ink

The Epson inks are from the manufacturer, not a refill or imposter. I’ve been using these for years. The price is the same as the manufacturer or a local retail but thru Amazon I don’t pay shipping and I get them the next day
