How can the mobile phones be attached? Which mounting options are available?

Belt clip

The belt clip is a kind of cup holder. The clip, which is attached directly to the smartphone, stays on the device even when you hold it in your hand.

Leather case

With the leather case the clip holder is fixed to the belt. When the user takes the mobile phone off the belt, the clip remains on the belt. By pressing the spring (right and left) the leather pouch is released from the clip.
