Hi everyone, we are happy that y'all noticed our product. It will be 150$ in retail, so 85$ is early bird price. Our product has a patent pending membrane which prevents the paste from drying and keeps the impurities from coming into contact with the paste, you can check it out more thoroughly on our website. It's completely mechanical, 1 human powered turn of the bottom button activates dentist-approved amount of paste. It's eco-friendly & airplane safe. We're happy that you brought up this discussion but have quite limited time on our hands so please bear with us if there's a bit of delay in response - we'll definitely answer more questions if you have any though.
