Mastic was chewed by cavemen back in the day - now picture a caveman...did you visualise a person with a razor-sharp jawline? 

Mastic gum was their secret, and now it's yours too!

Mastic is also recommended by Dr. Mike Mew (a British orthodontist who incorporated mewing into the world of dentistry) as one of the best ways to exercise the jawline.

For optimal results, try ROCKJAW with mewing exercises.

Be sure to chew evenly on both sides, taking breaks.

Stack as many ROCKJAW crystals as you desire and chew for 30 mins to 2 hours daily. Ensure even chewing on both sides, taking short breaks.

Just like any muscle, consistency is key to maintaining and developing your masseter muscles for that striking jawline. It is important to continue working your jawline muscles for long-term results.

🌡️ FOR BEST RESULTS, KEEP REFRIGERATED OR STORE IN A COOL, DRY PLACE.

Choking hazard, keep away from children under the age of 10.
