Jawliner® Hard Jwaline Chewing Gum - Sugar Free Spearmint Tough Jaw Gum - Jaw Exerciser Strong Mewing Jawline Mistic Gum - 2x Harder than Regular Chewing Gum 33 Grams (12 Strips)

Even with the 2x is making difference with 2-3 hour workout. It has no sugar, but still have flavor, would be amazing that there would be a plane version!

Flavor fades quick, so not sure it matters which you choose. I can see how this is a good jaw workout, gum is very tough to chew. Just be careful you’re not giving yourself a headache with it. Vegan product!

Not great better options out there gum isn’t that hard need 2-3 pieces and still won’t be great, flavor of gum is nice though taste like natural spearmint.

It tastes great!

I really like this product! It feels incredibly soothing and comfortable on my skin, and I've already seen noticeable results. I gave it 4 stars because it exceeded my expectations, but I think there's still room for a bit of improvement.

Tiny! Don’t waste your money

Jawliner is less hard than mastic gum but still hard enough to get the job done. Great flavor while it lasts.

I normally prefer softer gum, but decided to try this one because I was curious about it, plus it is sugar free and I like mint. It is definitely harder than regular chewing gum, but after some chewing it is just like regular chewing gum. I find it expensive (almost 60 cents per strip) and I am not buying it could have a large effect on the jawline (it definitely doesn't after the 12 strips the box comes with). Flavor is good but, as most chewing gum, dissipates quickly. I would probably not buy again but I would definitely recommend trying, specially if having a different jawline is important to you.
