There are various accessories for iPhone, but most of them are made of leather, wood, plastic, metal, etc. The material of the back cover of this iPhone is wonderful. It uses the concrete that we often see, and it is cut out piece by piece. Yes, each piece is unique. Can this back cover be bulletproof?

This concrete iPhone back cover is cut from a large piece of concrete. From the picture, there are obvious traces of use, such as scratches, damage, etc., making each piece unique.

What's more interesting is that the concrete iPhone back cover is thin after cutting and has a certain degree of toughness. It can be bent to a certain extent, but I don't know whether it will be as crisp as a biscuit.

At least from the product pictures, the thickness of this concrete iPhone back cover is acceptable. However, it may feel strange. You can touch the cement floor you often walk on.

However, from the design point of view, this concrete iPhone back cover still has a sense of walking on the moon. At the same time, this concrete iPhone back cover seems to have considerable hardness, at least much better than the original fragile back cover.
