iPhone5 cover with a mustache attached to a chain.
Chain is at least 24cm long. You may attach a large jumper ring and or a carabiner hook to the end of the chain. This cover could be useful when skydiving, riding your bike, living the goodlife on your 80ft luxury yacht, scaling the Himalayas or just the regular stroll across town.
Additional advantage of the plastic chain is that it wont scratch your phone.
