Sexy at 71 super mod..
Have you tried a multi meter on them..just wondering if they have a voltage of any kind coming from them..hows about that for a random thought..Had the same issue with the Golden Sun rice. As I had a bit of time to spare I checked the lengths of the grains. Not much there. So I checked the grain diameters at four places each to get an average. Keep your fingers dry or the little beggars start swelling on you.
I sent them an email. You can relax, no traces of nuts.
