I saw an old thread that had a lot of disinformation in it. Jarts and or lawn darts are not illegal to own, use play with or gift. They are illegal to sell. State laws will also apply but Federal law is you can own them. I have 4 sets and pick them up when I can find them cheap. They will only grow in value. I was told by an attorney if I want to sell a set do it at a swap meet cash anomalously. I am not saying to do this or that one should but this is what I was told.. So if you have them hang on to them. Just like a gun don't let your kids play with them, at least alone.
