This set is made of brand new PC+ABS materials for hardshell exterior, which make the luggage more durable, lighter, and impact-resistant, protecting the case from scratches and keeping cases beautiful after a trip. 
The bottom of the case is eight-spinner wheels, which are known as aircraft wheels.  The luggage has passed tests such as drop testing, mileage testing, and other functional testing to ensure its high quality for long-term travels and business trips.
Besides the case, there is a TSA lock, which means only TSA agents are capable of inspecting your bags without damaging the lock when traveling. The lock and full-zipper design can protect your privacy to the maximum extent.
