I received the TN221 (black, 1 pack) and it was compatible with my HL-3140CW. Haven't changed cartridges for a long time. Black was nice to get since we use it the most, but the listing doesn't exactly mention "Contents: 5 sets of replacement cartridges of compatible toner for Brother TN221 TN 225 (2 black, 1 cyan, 1 yellow, 1 magenta)".
