The material is 10k
The toroids were in good shape and appeared new. I calculated that the material is 10K for this batch. It would be nice if they would list it in the description.

About 5000nH/T^2
Measured slightly higher than 5000nH/T^2 at 1kHz when wrapped with 10 to 20T and no bias current. Inductance dropped to about half it's L_0 value when biased with about 1.2 A*T. But my setup was fairly crude, so the real A*T for L_0 / 2 is probably a bit higher.

10 turns #30 WW wire produced a tad over 500 uHy. Good value at a buck each will buy more
10 turns #30 WW wire produced a tad over 500 uHy. Good value at a buck each will buy more. good for RFI control and hot coax cable outer shield and actually some audio filter projects since it does not take a lot of wire to get in the mHy range. thank you Bob, KE6F

Works good, haven’t tested saturation yet
These cores seem to have an AL of 6000. 16 turns gives 1.5mH, 19 turns gives 2.3mH. I’m learning on YouTube how to wind. Will update this review when I know how many amps I can push through flyback converter.

Handy for Amateur Radio projects
I keep some of these on hand for various Ham radio projects that spring up occasionally. They are as advertised and seem to be fair priced. The only reason I held back on the #5 star is that I could not locate any sort of documentation as to their make up. These are probably more useful to an experimenter designer, like myself, than to engineering designers. Still a good deal.
