Is it safe to train with the Jawliner?

Our team has spent a long time researching the best materials, so that everyone can train their jawline in a healthy way.
Then we landed on 100% BPA and PVC food grade silicone. This new material is improved for a better grip and a stronger bite.

The improved material guarantees longer consumption without losing power and strength. The longer shape and the holes provide more resistance when biting and result in a better workout.
No damage to the jawline?
No, only with excessive use. So read the instructions carefully before using the Jawliner. The ergonomic design is specially made so that the Jawliner does not cause any damage.
Have you had any problems with your jaw before? We advise you to visit your doctor first for confirmation!
