I think so too(they do not contain active substances).
But on sites which sell spores prints do not answer my letters, On these sites it is written that spores are not sent in the countries which have not signed any contract (for example state of USA - California).
Some years ago I were in the Netherlands...if I knew then with what problem I shall deal now...
I have written many letters, but to me one have not answered. On one forum to me do not want to talk on this theme(when I ask to help, to me write that do not understand about what there is a speech and that never saw anything similar).One person has made the assumption that I privacy officer, I do not understand why so occurs (I am in Russia and my ip-adress easily can be checked up).
Give, please, any good advice...?
I already simply do not know what to undertake for the decision of this problem!
