The version with clasp is very nice and allows to properly protect his toy. However, the clasp (which is the only downside of the cover) is quite impractical in the set. It is made of a very rigid leather (or a rigid material covered with leather) to be pressed against the edge of the device so that it "snaps". Unfortunately, when it is "clipped", it becomes very difficult to reopen the case again because ... the closure holds up well anyway!
See long term if the leather does not leave traces on the edge of the iPhone by rubbing it by opening and closing the cover.
But overall, great product. Again, congratulations to German of StilGut.
