As our suitcases are only made out of premium PP, PC and the material TPO which is exclusive to Eminent it is highly unlikely that the shell of the suitcase will break. In case a shell breakage occurs as the result of a transport damage we would kindly ask you to contact your airline first as this damage cannot be repaired. In rare cases a broken shell can also be resulting from a material defect. If the damage occurred during the warranty period please kindly contact our repair service for further evaluation.
