The toner and drum unit arrived safely in a labeled box, each sealed in plastic bags. Instructions for resetting the drum unit counter were included. Though identified by specific part numbers, it's unclear if they are original manufacturer products. They are compatible with various models, but I am specifically reviewing for the HL-L2390DW. The installation process was simple, and the test print was flawless. Everything appears to be in good shape so far, but I will provide an update if print quality diminishes or the lifespan is shorter than expected.
