If you have a Brother labeller that uses "M Tape" carts, a word of warning- stick to those with black text. The fade resistance of the red text is poor, but these blue ones are even worse... shockingly bad.
I'd noticed that while the blue text started out vibrant, it had serious fading problems. So I printed off four labels (black on yellow and white, red on white and blue on white) and left them on a south-facing window ledge for three weeks in the late September Scottish daylight.
The black tapes did fine, whereas the red faded quite badly. But the blue was worst of all- after just one week its intense colour had faded noticeably. After three it's a pale bluish-grey against a slightly yellowed background, already bordering on illegible in poor light. THREE WEEKS!
You might not be planning on leaving yours in the window, but even those exposed to indirect daylight from a window (or brief periods of sun shining in) will fade badly, often within months. Even when it's still legible, the faded text goes an ugly greeny grey shade.
While the machines are decently priced, Brother clearly make their money on the expensive tapes. That in mind, this tape's performance is disgraceful. If you already have a Brother labeller, stick to the black text tapes (they seem to hold up quite well), or watch your labels fade into ugly unreadability.
