Query: Horrible smell

I purchased this with the intention of putting it in a doctor kit I'm making for my children for Christmas. I received it today and out of the box it has a terrible odor; similar to an item kept in moth balls, but way more intense. I don't even want to take it out and touch it to see if it works. I'm going to try to air it out on the deck for a few days and see if it helps. I can't give this to my children like this. I'm dissapointed because this was recommended on a blog which is why I chose it. There were others that were less expensive and some that even included a stethoscope.
