Product Description Our story... How GUMBELLS started ....By Kris (Founder, London UK) The story started way back 25 years ago. I would watch my mother pulling faces in the mirror and over pronouncing A,E,I,O,U. To be honest, at first I thought she was going crazy. Fast forward 25years, I realise I was the crazy one! After getting married, having kids and gaining one too many pounds (weight) and no longer going to the gym I decided enough was enough and made it my goal to lose the weight. However after losing 26lbs, my face still remained puffy. I spent 3 years researching and trying every one of the limited tools out there to improve my facial look. I tried the a vey popular ball you chew to exercise your facial muscles, but was not keen on this product at all. Saliva would remain on the product which I found very unhygienic. I also felt it wasn't hitting the correct facial muscles and maybe was even pushing out the front teeth (that's the last thing I wanted!). I also tried some large tabs that broke in a week and only seemed to slightly work the masseter muscle and nothing else and are a choking hazard. I knew that the solution would have had to be something that was natural to use, something that provided resistance to as many as possible of the 57 facial muscles. Working with teams in 3 countries, the first version of our jawline hard gum was formed. GUMBELLS is our 3rd generation of gum, developed specifically for facial fitness and Jawline shaping. 1MONTH-SUPPLY GUMBELLS 1 1/2MONTH-SUPPLY GUMBELLS 3 MONTH-SUPPLY GUMBELLS units to use 4-5 times per week 20 30 60 premium metal storage tins 1 1 2 GUM-BELLS Jawline Gum Normal gum flimsy silicone trainer Drooling jawz trainer cleaning before use required NO NO YES and also after YES and also after durability ✓ to soft not suitable for jawline exercise breaks very easily ✓ saftey FDA (US) approved packed full of Aspartame and other cheap filllers severe choking hazard used with front teeth-misalignment of the face issues and not effective can be used anywhere YES YES Not in public also will need to be cleaned soon after use definitely not in public resistance 12 times more than normal chewing gum and 2.5 times bigger Even if you chew 4 pieces of gum in one go, this is just increasing the quantity not resistance.
