JawlinerHard 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.

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.

This is like any other gum but stale. Imagine a really stale piece of gum, it'd be hard and brittle. This jawline gum is hard and brittle as well. But thats not a bad thing. The firmness of it is likely due to the need to be hard to chew in order for muscle to build your jawline. The flavor is perfectly fine and helps your breath as well. Maybe a bit pricy for what it is, but it is a unique product and has a bit of a novelty factor to it too.
