Genuine OEM Brother MFC-J680DW Ink and Supplies
Brother LC-201 and LC-203 give the MFC-J680DW two four-color ink families. Both have individual cartridges and a three-color pack, and LC-203 adds a black two-pack.
Those formats are all genuine Brother ink at Toner Buzz. Choose the correct family, then select one color, the cyan-magenta-yellow pack, or the LC-203 black pair to match the number and colors of cartridges you need.
