The latter unfortunately does not.
The punched edges of the openings and the circumferential center line are not deburred or only insufficient. So you always have the feeling that they get stuck somewhere or to withdraw along a sharp edge.
At the bottom edge (I had two cases, because I thought it was a mistake the first shell) is a left side about 1 cm wide body that is simply finished awful and was not finished. Here can be found a distinct ridge. It can be assumed that it is the bridge connecting point of mass production. Unfortunately, it is exactly the place where the little finger (right hand) holding the cell phone from the bottom. The point is not trimmed and even reworking with abrasive paper (3000) makes it not optically better. Without rework / loops you always have the feeling of having to push away the little finger.
Sorry, but that disqualifies this shell easy!
