Bought some plastic travel bags from amazon, theres a noticeable plastic smell. friend insists the fumes are toxic and to not use the bag to store toiletries. is it best that i air it out, toss it out or just use it as is?

Wash the bags if washable and air those out. Putting toiletries in the bags is unlikely to be harmful.
