HotWay 26 Inch Aluminum Frame Luggage with Spinner Wheels, PC Hard Shell Suitcase with Cup Holder, Zipperless Luggage for Business Travel

The suitcase features a TSA-approved lock, allowing airport security to open and inspect the luggage without damaging the lock. This provides convenience and security for travelers, especially when traveling to and from the United States. No key is included; you set your own combination.

This suitcase does not have a double wheel function. It uses standard spinner wheels, which provide good maneuverability on smooth surfaces but may not be as stable on uneven terrain. Double wheels would enhance stability and reduce strain when moving the suitcase.

This suitcase does not have an expandable function. The capacity is fixed at 78L, which may limit flexibility for travelers who need to accommodate additional items during their trip. An expandable function would provide extra space when needed.

This suitcase does not include a brake function. A brake function would prevent the suitcase from rolling away on slopes or in crowded places, providing added convenience and safety. This feature is particularly useful when temporarily stopping the suitcase on uneven surfaces.

This suitcase does not include a USB port function. A USB port would allow for convenient charging of smartphones or other devices while waiting at the airport or during travel. This feature is useful for keeping devices charged when outlets are not readily available.

This suitcase does not have a front open function. A front open function would allow for easy access to items stored in the front compartment without fully opening the suitcase. This is useful for quickly retrieving documents or small items during travel.
