A TPU (Thermoplastic Polyurethane) phone case is made from a material that combines the best qualities of plastic and silicone. It’s flexible like silicone, making it easy to fit around your phone, but also durable and resistant to oil, grease, and abrasions like plastic. TPU cases provide a solid level of protection from impacts and drops, and they can be designed with various levels of thickness for extra protection or slimness.
