Would you like a mobile phone chain on your favourite mobile phone case? No problem. The universal mobile phone chain adapter can be attached to any back cover (hard case is an advantage), provided it is firmly attached. Simply clamp the adapter between your cover and the smartphone and you can attach a mobile phone chain to it. This makes it easy to carry your smartphone over your shoulder like a handbag or simply around your neck like a necklace. Your hands remain free, your mobile is always at hand and, what's more, your smartphone is kept safe with you. Notes: The scope of delivery only includes the universal mobile phone chain adapter WITHOUT the mobile phone chain or protective case! Make sure that the cover fits snugly around your mobile after inserting the adapter.
