Jawzrsize Custom Fit Series

The #1 Way To Strengthen & Redefine Your Jaw

"I can easily see the dramatic change that happened in my face" - Eric W., Jawzrsize Customer

The Jawzrsize Custom Fit provides a unique workout so that you can slim, tone, tighten or strengthen your face, neck and jaw... In just a few minutes a day!

Perfect for Men or Women who want to...

  • Redefine their jawline
  • Reduce double chin
  • Strengthen their jaw, neck, and face for sports performance
  • Restore their youthful appearance

Jawzrsize is designed to work out the full range of motion of your bite, giving you a stronger fuller look- the kind that face fillers can only dream of. This small, durable, and affordable piece of equipment will leave your face and neck visibly more toned and youthful.

The Custom Fit Series is custom fit to your teeth!

It features Boil-To-Fit Bite Strips that fit flush like a mouthguard. The Custom Fit series is more durable and longer-lasting than the Pop 'N Go Series!

Within seconds you'll feel the the 57+ muscles in your face, neck and jaw all being activated.

Wondering where to start?

We recommend starting at Level 1, and working your way up to Level 4. Here is a breakdown of all 4 Custom Fit Levels:

  • Level 1 - 25 lbs of resistance (Blue)
  • Level 2 - 35 lbs of resistance (Pink)
  • Level 3 - 45 lbs of resistance (Purple)

Each Level provides an increase in resistance to your bite, so you can keep making progress until you've reached your goal. Once you reach your goal, make sure to do a few maintenance sessions a week so that you don't lose your progress.


Each unit comes with:

  • 1 Jawzrsize Unit
  • 2 Pairs of Bite Strips (4 Strips Total)


  • Hands-free workout for your jaw, face, and neck
  • Chisel your jaw and achieve a stronger looking face
  • Reduce double chin, never look awkward in photos
  • Activate 57+ muscles in the face
  • Increase blood flow to the face, oxygenate cells and look youthful
  • Slim and tone the face for a defined profile at various angles
  • Increase metabolism to help you lose weight
  • Reduce cravings by satisfying the desire to chew and eat
  • Relieve stress and tension in the mouth and face


1. Choose

Choose your Jawzrsize device.

If you're just starting out we recommend the beginner (25 lbs resistance). As you progress, work your way up to the elite level (50 lbs resistance)

2. Fit

Fit your Jawzrsize unit to your teeth.

Boil in water for 20-35 seconds, then remove Jawzrsize and place comfortably between your teeth. Bite down for 10 seconds to fit your unit to your unique bite! 

3. Activate

Place in between your front teeth.

With every bite, you're activating the 57+ muscles in your face and neck that define your jawline.

4. Measure

Measure your results!

With just a few minutes a day you will begin to notice a HUGE change in the definition of your face/jawline.


By targeting the primary chewing muscles known as the Masseter Muscle, Jawzrsize actives and strengthens areas of the neck and face that are rarely exercised. Leaving our faces rounded and our jawlines undefined.

“A Few Reps A Day Keeps The Double Chin Away!"

Since facial muscles are small, they will respond quickly - meaning you can begin to re-shape your physical appearance within the first few days!

5-10 minutes a day, 4-5 days a week is all you need.

And you can work them out anytime, anywhere!

    Great product!

    I love the product! I mainly use it in my car and saw results in a few weeks. As an unexpected benefit, i saw it helped w my bad habit of biting my nails! Instead, id pop the jawsrzice in get a face work out. The company has been a pleasure to work with because of some damage that i caused on one of my products from unnecessarily, biting down too hard . They offered to send me a new one at no charge. Im happy with my purchase!
