This suitcase does not have a TSA lock. This means that if airport security needs to inspect your bag, they may break the lock to gain access. Consider using a TSA-approved luggage strap for added security and to allow security personnel to inspect the bag without damaging it.

This suitcase does not have double wheels. Double wheels offer increased stability and smoother rolling, especially on uneven surfaces or when the suitcase is heavily loaded. The single wheels on this suitcase may be less durable and prone to wobbling.

This suitcase does not have an expandable function. An expandable function allows you to increase the suitcase's capacity by unzipping an extra section. This can be useful when you need to pack extra items or souvenirs during your trip. Without this function, you are limited to the fixed capacity of the suitcase.

This suitcase does not have a brake function. A brake function locks the wheels, preventing the suitcase from rolling away on slopes or in crowded places. Without this function, you need to be mindful of where you place the suitcase to prevent it from rolling away unexpectedly.

This suitcase has a USB port function. This allows you to charge your smartphone or other devices while on the go. You will need to provide your own power bank and place it inside the suitcase to utilize this feature. This is convenient for keeping your devices charged while waiting at the airport or during travel.

This suitcase does not have a front open function. A front open function allows you to access items stored in the front compartment without fully opening the suitcase. This can be useful for quickly retrieving documents or small items during travel. Without this function, you need to fully open the suitcase to access your belongings.
