Legal implications of home made toys

I’ve had this idea for awhile. I’m thinking of doing just 100 home built and sell them on ebay or something. Just for the experience of doing a new product entirely myself.

I will definitely test a few myself doing everything a 3 year old would do. I think I still have access to my immature child inside;)

Having said that, if it ended up being a huge hit and selling out quickly for a reasonable price, I might look into growing it. Time will tell. I’m still very far from even having a prototype, so I won’t hold my breath.
