The beads are made of 100% silicone. Silicones are mainly made of the basic element silicon (silica) and oxygen. Better known as quartz and in small form, the main component of sand. 12% of what can be found on and in the earth's crust consists of quartz. This is the most abundant mineral on Earth. When carbon and hydrogen are added to quartz, long chains of silica molecules are formed to form silicone. A rubber-like, unbreakable material that has many advantages and has a very long life.
