Weak Magnetization
Compared to Metallic Ice and any of the 5D UCC magnetic pigments, I had to use a lot more of this pigment in my suspension base and still found it very hard to magnetize. The pigments barely reacted to my 30lb horseshoe magnet, and was even harder to create a cat eye. This seems to be a consistent issue with magnetic pigments sold here for about $2. The $6-$10 pigments do not have this issue. Because of my good experience with the other magnetic pigments, I don't think it’s user error.
