The balls are composed of ferrite, a ceramic oxide material chosen for its performance and safety benefits. This side of the glove helps break up congestion in your lymphatics at a deeper level.
Here's what ferrite does for your body:
Muscle recovery - deep pressure helps break up internal tissue adhesions and knots
Increased circulation - rubbing the skin causes local vasodilation, rushing oxygen and nutrients to sore tissues
Pain relief - physical stimulation activates sensory receptors, temporarily overriding pain signals sent to the brain
Improved flexibility - regular use loosens surrounding fascia, increasing joint range of motion
And why ferrite as a material:
Excellent hygiene - as a ceramic oxide, it is highly resistant to corrosion, body sweat, and massage oils
Easy to clean - smooth surface won't trap bacteria, allowing easy sanitisation between uses
Temperature retention - holds temperature well, so you can cool the tool in ice or warm it up for thermal therapy
