What would make a dildo "industrial strength"? What industry would require such strength? Surely the porn industry, but are non-industrial-strength dildoes so flimsy that they will fall apart regularly? I kind of feel like if you need an industrial-strength dildo, there are far more problems than an industrial-strength dildo would solve.
Industrial strength can mean two things here. Either it's the size of the dildos, or it's the fact that they can be used almost 24/7 for years on end without noticeable material degradation.
