Nice, what's their permeability? Do they stick strongly to a magnet?
They sticks nicly to a magnet. Hard to release from a neodymium magnet. I don't know what permeability there is on these, but they are suitable for low distortion audio coils which needs low DC resistance and high inductance, so I guess the saturation point is quite high. The cores are also non-conductive.

Regarding shipping of these cores. A letter up to 1kg and 2 to 7cm thick costs approx 25USD outside Europe, and â,¬15 inside Europe. The weight of each core is approx 27 grams.


Edited the pricing because I was looking at the wrong product in the postal service price list.
