I can assure you that I know one type of foam from any other, and these parts were shipping in big bead, white styrofoam found in a typical ice cooler. The parts might survive that type of shipping from half way around the world, but I was not going to accept it.
My money was refunded, and I was allowed to keep the parts. I may give them a try at some point. Te other interesting thing about these parts was the logo on them, it was not a Microchip logo.
