Carry On Suitcase Hardside Built In TSA Lock & USB Port Silent Double Spinner Wheels Maximum Underseat Carry-On Bag For American & United Approved Airlines( 18x14x8")

The integrated TSA-approved lock allows airport security to inspect the suitcase without damaging the lock, providing added security and convenience for travelers. This is particularly useful for travel to and from the United States, where TSA inspections are common.

The suitcase features multi-directional 8 easy glide super silent spinner wheels, which can be interpreted as a double wheel function. This provides enhanced stability and smooth rolling, even on uneven surfaces or when the suitcase is heavily loaded, reducing strain when moving the suitcase.

The suitcase does not have an expandable function. This means the capacity is fixed and cannot be increased, which may limit packing flexibility for longer trips or when purchasing souvenirs. Consider this limitation if you often need extra space.

This suitcase does not include a brake function. Without a brake, the suitcase may roll away on slopes or in crowded places, requiring you to keep a constant hold on it to prevent unexpected movement and potential accidents. This could be inconvenient in certain situations.

The built-in USB charging port allows for convenient charging of smartphones and other devices while waiting at the airport or during travel. This is useful for keeping your devices charged when outlets are not readily available, enhancing convenience during your journey.

This suitcase does not have a front open function. Accessing items requires opening the entire suitcase, which may be less convenient when you need to quickly retrieve documents or small items. Consider this if you frequently need to access items on the go.
