Its strickly designed for envelopes, 80# index and other porus materials...This re-manufactured cartridge was produced in our own state of the art facility, with the finest cleaners, pure DI-water for flushing and a great Pigmented Ink. No other webpage company makes there cartridges, they outsource them....We stand behind our products... if you don't like them, and want to return them within 30 days, I will even pay for the shipping back...
