Our silicone is 100% PBA and PVC free. In addition, our manufacturer has a valid F.D.A certificate, which is checked at regular intervals.
As we sell in Germany and the EU, we are subject to strict regulations and are therefore obliged to have our JAWLINERs regularly tested for harmful substances by an independent laboratory.
We are regularly tested and certified by the PICA Institute from Berlin. Since 2021, our JAWLINER as well as the packaging have been inspected and awarded by the Bavarian Health Office.
If you are still not sure, we recommend JAWLINER Fitness Chewing Gum instead. The chewing gum is not made of silicone but has the normal ingredients of a chewing gum. Nevertheless, JAWLINER Fitness Chewing Gum is the hardest chewing gum in the world and also wonderfully suitable for training your jaw and facial muscles.
