Haidms Matte Black Interior Privacy Door Knobs (4 Pack)

I've got a 4-pack of these Haidms interior door knobs in matte black. They have a modern look with a square rosette and a round knob. These are the privacy version, so they're meant for bedrooms or bathrooms where you need a lock. They're heavy duty and still in the box. Just looking to clear out some extra hardware from a project.
