WHAT CHANGED?
Modern diets = weak jawline

First I thought it's expensive, but they are handpicked. I've tried other brands, you can clearly tell the difference.

Bought to replace my chemical-laden chewing gum. I personally like the taste. What matters most is the quality & I'm satisfied.

The mastic tear size is perfect. Toughness isn't overly hard or soft - perfect.
Bartosz. Z
So far love the way you can chew on it forever! A healthier chewing gum alternative.

Picture a caveman. You automatically visualise a grizzly man with a sharp, chiselled jawline...
I did too.
So what happened between then & now?
Food got soft - causing atrophy of our jaws = weaker jawline.
When our facial muscles are not utilised, they begin to shrink - like skipping the gym.
The Fix?
Let's travel back in time...
...that's where mastic gum steps in.
Stackables contains hand-picked medium to tough crystals, ensuring you get the perfect, customisable chew.
+ it's great for your oral & gut health.

FAQ's
We hand-pick each and every crystal to ensure only the finest ones are in your tin - a process that no other brand does.
Other Brands:
Other brands mass-pack mastic gum, meaning a lot of your crystals will be soft and sticky, since the toughest crystals are rare.
ROCKJAW:
We filter the soft crystals from the tough ones to eliminate the softer crystals - a process that takes several hours.
Both MAX Edition and Stackables are hand-picked and packed - a laborious process.
The Difference:
The MAX Edition contains the toughest and largest mastic gum tears.
These are very rare, especially during the summer months, meaning we're only able to extract a handful of tough and large mastic tears each month.
The Stackables range contains slightly smaller, but tough crystals, designed for a more controlled and intermediate chewing experience.
The toughness of the Stackables range varies from medium to very tough.
Here are the products that can be rechewed.
- The MAX Edition can be chewed for a total of three times.
- Stackables can be chewed for a total of three times.
We recommend rechewing these products to maximise value & prevent waste.
The Tuff Gum range is NOT suitable for rechewing.
Unlike regular gum, mastic gum never dissolves and retains the same hardness the second you chew it - making it suitable for re-chewing.
It depends.
The Stackables range is best for those wanting a tough, yet intermediate chewing experience. It is best to maintain long-term results, or those starting from scratch.
Doesn't sound like you?
Fret not. We have a range of other products that may be better suited to you.
If you're looking for the best, toughest and natural experience, the MAX Edition is the ideal option for you.
This product is hand-picked, containing only the most premium & toughest mastic gum crystals.
The Tuff Gum range is ideal for those wanting a flavoured experience without compromising toughness. it is roughly 8x tougher than regular gum.
