The body of MPencil 2 is made of silica gel, which is also known as silica gel, silica gel and oxidized silica gel. It is a kind of highly active adsorption material and belongs to amorphous substance. The main component of silicone is silica, which is chemically stable and does not burn. Generally speaking, silica gel can be divided into two categories of organic silica gel and inorganic silica gel according to its properties and components. Silicone shell properties wear resistance and non-slip.
Ordinary accidentally fell, or very resistant to fall, if you want to specifically drop it is hard to say
