In order to avoid damaging the cabin, the tool case with hard surface i.e. metal/ABS tool case, is not allowed to be brought into the cabin for the maintenance, according to international convention. Thanks to our tools case that was specially designed for the collection of aircraft maintenance tools and made it possible to protect the cabin. 

Duo to this reason, Lufthansa decided to designate our tool case as the sole one to implement the cabin maintenance in PR China.
