After a long wait, Google finally released the mid-range Pixel 4a today. As usual, Google also officially released a matching mobile phone case. Although this phone case looks the same as the mainstream knitted phone case on the market, Google said that the biggest highlight of this phone case is the material. Google said that the biggest highlight of this mobile phone case is the use of more than 70% of renewable plastics, which means that it has good environmental protection. 2 recycled plastic bottle materials can make 5 such mobile phone cases. Whether it is standard wear or cracks when dropped, the jacquard pattern on the back of the phone case can cover these damages well. Google said that you can even throw these phone cases into the laundry to clean them in case they become too dirty and unsightly. In terms of protection, Google said that this phone case uses "edge-to-edge inner microfiber" to prevent drop damage. The protective case also has a raised edge, which can keep the phone display slightly elevated when you put the phone face down on the surface. All in all, when it comes to fall protection, it seems to be a fairly standard protective cover, but it only adds to the perspective of mainly using recycled materials.
