What is a silicone phone case? Many people know silicone phone cases frm the ones that used to be made for very early phone models, just at the beginning of when phones became smart. They were very soft, a little bit sticky to the touch, and they gripped the surface they were placed on. They were very popular for a while. Modern silicone phone cases are typically made from ‘liquid silicone’. You may wonder what a liquid silicone phone case is. Liquid silicone is different from old soft silicone in that it is much harder and similar to a gel phone case in its elasticity. Typically, these cases are a matte finish, are light to the touch, and can resist fingerprints and dust. They cover the back and sides of the phone and protect them in the same way that a gel cases do. They are very popular due to the feel and finish they offer.
