Hi, last year, I ordered the wrong cartridges for my brother printer. I opened up the black one and saw that it would not fit my printer. So I have a brother 331 black and a brother 331 blue magenta and yellow cartridges. Part number is TN331BK and then TN331 3 pack. I got the right ones for free but they would not take the old ones back. I am willing to send them to you if you pay shipping. Contact me at (e-mail address removed).
