What to know before buying

Listing details to confirm

The listing describes the product as a 2-pack and its title says “(2 Black)”, but the included-components and box-contents fields each state “1”. The actual number of cartridges is therefore unclear. The 3,000-page yield is a listing claim based on 5% coverage, not a guaranteed yield for every document. Confirm the pack quantity and your exact printer model before buying.
