It might seem that the shape is simple and doesn't involve much engineering, but that's not the case. Inside, there's a rather ingenious solution to ensure the shape holds, and our engineer spent a lot of time communicating with the production team, convincing them to do it the right way, not just how they thought it should be done.
The mouthpiece is made of metal and silicone with a leather cord. It's designed for multiple uses. The batch consisted of 50,000 units. The engineering was meticulously refined up to the industrial prototype. The product has been launched into mass production and is now on the market.
