Tech 21 processed in the edge of the envelope a special material. "D3O" called the orange material and usually has a tough but compressible consistency. If the material is exposed to a sudden but heavy load, it increases its resistance. In an explanatory video shows how someone like a thick ring puts a portion of this play dough-like D3O to their own finger and then firmly with a hammer strikes without taking damage. In the event of a crash of the iPhone, this material therefore very good protection to the sides without going too much into the width. In addition to this protective ground property, Case is distinguished from a truly flawless workmanship. The "flip" part snaps gently but clean and safe a closed. With the back of scratch-resistant TPU material, the PU leather cover is firmly attached, and provides additional protection. While holding the iPhone, it feels good and high quality. The iPhone is so good in your hand and you have a secure feeling. All buttons come with a slightly elevated pressure but precise use. From about the upper third of the back of the cover is, and shall be closed neatly around the base. There recesses for headphones and speakers. The charging port in the middle is only accessible with the flip open. What appears to be disadvantageous at first but is the stability of the flap. To make calls, charging, or other activities on the iPhone, you can also easily put the lid completely to the back. The inside of the flap is provided with a velvety-looking material and has a slit or slot for a credit card or similar .. Despite the cover of the display, the iPhone remains in my view acceptable narrow. It offers as an excellent all-round protection and the cover disturbs less than I would have believed. Overall, I absolutely can not fault notice to the Classic Shell Flip. The iPhone fits in like a glove and can also be easily re-take it. Those who prefer without Displayschutz- "flip" the go should look at the Tech21 "Classic Shell" is sometimes. It has the same properties without the protective flap.
