Your Pierre Cardin Voyager Luggage arrives ready for immediate use, requiring no complex setup. Simply extend the telescopic handle and begin packing. For compatibility, the Small (19) size (54.5 x 36 x 23cm, 38.9L) is designed to be cabin compatible with most airlines, but it is crucial to always check your specific airline's carry-on restrictions before flying. The Medium (25) size (65.5 x 44 x 26.5cm, 64.6L) and Large (28) size (76 x 50 x 31cm, 102.7L) are intended for hold luggage. To maintain your luggage's pristine appearance and durability, care is straightforward: wipe the ABS hard shell with a damp cloth to remove dirt or scuffs. Avoid harsh chemicals or abrasive cleaners, as these can damage the finish. Ensure the interior is dry before storing to prevent mildew.
