My friend runs a perfectly legitimate business making holsters for firearms, real, airsoft, whatever. Maybe just a step up above what you'd find in your army/navy surplus store.

Stripe's TOS expressedly forbids these, yet all they are is just a hunk of plastic not unlike those old tacky blackberry holsters that people used to have a few years back.

So yes, be in the "wrong business", you can't even sell a bit of plastic or leather because it's shaped wrong.
