The box says Taiwan, but it looks like I just found the answer. The MF-25B is the earlier Yageo prefix for what they now call the MFR-25FB series. The change came in the mid-late 2000's. Ex: their current 9k53 is MFR-25FBF52-9K53, the earlier number was MF-25-B-9.53K .
Also, I see that the current Yageo MFR- resistor kits have the identical part numbers as the MF- ones I bought 30+ years ago.

Same here. What's your overall impresssion of them? They seem like a good general-purpose resistor, tho I still favor RN60's in feedback positions.
We used them for lab proto circuits, and never had any problems. The price was right,
especially for their large prepacks. For my own audio stuff, I always use fresh parts
with mfr tracing, though. There's too much of my work involved in building stuff to cheap out.
