I find very successful

This bag has a small and smooth magnetic closure. The accounts for approximately .2 mm thickness for the flap (WxL = 20x25mm) on barely. It is especially advantageous that with plugged mobile abuts the tab the same and not dangling. Cons by the magnetic lock on the SIM or memory card I did not notice.
The color and feel of the bag itself like on top of that to me.
