Hi

What age "kids" are you talking about and in what setting?. There are some basic hazards associated with some of these pens. I realize you probably are looking for one to sell rather than to use, but the issue is still the same. Once upon a time, kids survived things like wood burning kits that today would get you arrested for child endangerment. I'm not trying to turn this into a political discussion, only to try to get an idea of how well protected a pen you might have to have.
