The new design makes the JAWLINER 3.0 more than 80% longer lasting than its previous version, the JAWLINER 2.0. Two ultra bite-resistant outer layers protect the inside of the JAWLINER even from particularly sharp teeth. The surface is also equipped with a non-slip material for an even better grip on your molars.
Different Hardness Levels
As before, the JAWLINER 3.0 comes in three degrees of hardness. Compared to the JAWLINER 2.0, the degrees of hardness are even more differentiable. For all those who want to successfully train their jawline and facial musculature, we recommend starting with the JAWLINER Beginner. Those who have already gained some experience with jaw muscle training are welcome to train with the JAWLINER Advanced. We only recommend the JAWLINER Expert to those who find training with our JAWLINER Advanced too easy. The Expert level is not for starters! With 80 kg/cm2 your jaw presses almost as much as you do on the weight bench.
1 Year Guarantee
We give all customers a 1-year guarantee. If, contrary to expectations, your JAWLINER breaks during jawline training, send us an email and we will send you a new one immediately. Within the first year after the date of purchase you can make use of the JAWLINER guarantee at any time!
Deliberately, we have developed our JAWLINER in a natural way - unlike other Jaw Trainers with the known health problems. The JAWLINER stimulates the chewing muscles in a natural and healthy way without putting more strain on the jaw joint (TMJ) than eating a tough piece of meat. The mouth does not open more than necessary during training and exerts pressure with the molars which are designated for that task. More detailed information can be found in our blog article on the subject of health.
