The Symmetry Smartphone Case for Samsung Galaxy S21/S21Plus and S21 Ultra 5G from OtterBox features a DROP+ protection, anti-microbial technology, and is made with more than 60% recycled plastic. The single-layer case slips on easily and can withstand three times the drops of the MIL-STD-810G 516.6 military standard. To keep your hands germ free, the case has been infused with a silver-based additive that works to prevent the growth of common bacteria.
