Now practically everyone knows how poisonous they are. It´s no ideer to say you didn´t know.
If you sell them you must have an insurance and let the buyer sign a that he read a paper which explains how dangerous they are.
In Sweden we had an instance with the man three days in hospital and the wife two days. He is not fully recovered. It was three years ago.
One man in Gothenburg had to retire after a Paly poisoning. There are more cases here.
When a layer gets grip on such a case you have big trouble.
I have a small shop but I dont dare to sell Palys.
