No, we have had zero reports of people swallowing CHISELL by accident. We get a lot of comments saying that CHISELL looks like a choking hazard but none of them come from actual users. If you use CHISELL correctly, it’s virtually impossible to swallow accidentally. And if you were to try to deliberately swallow it you would still fail because the tabs are too large and the matte surface texture creates strong friction which won’t let the tabs slip into your larynx. Furthermore, CHISELL 3.0 is designed in such a way that even if it ends up in your air passageway, the air will flow through it freely preventing you from choking.
