WHY TITANIUM?
Lightweight and strong - It has the highest strength-to-density ratio of any metallic element. It weighs almost the same as aluminum but is stronger than steel.
Corrosion resistant - It is highly resistant to corrosion even in sea water, aqua regia and chlorine.
Biocompatible - It is non-toxic, non-allergenic and perfectly compatible with the human body.
Durable - It is more durable than gold and has become a popular choice for designer jewelry.

How to use it:
Hold spinner in one hand and use the other hand to spin it rapidly with small continuous strikes to keep it spinning indefinitely. With practice you can spin it using one hand only with the fingers to start and stop spinning.
