They look to be shirataki noodles, which are made from yam I believe. I haven't tried that particular brand but have tried the brand we have here in Canada. They are okay in a stir fry. They are a little on the rubbery side, but like spaghetti squash, still not pasta. Rinse them well, boil briefly, then pan fry them to remove moisture. Worth a try if you are craving pasta.
