Dear seller, I have 5 other such luggage purchased from Japan. I have been using travel luggage's together with my family since last 12 years. This is the first time the bag quality is found very poor. At one corner of the luggage I found the screws and wheels are loosely attached. During my first travel I found the luggage can not be pulled and rolled on the floor. I am so upset with such condition. If I get your kind cooperation to improve this that will prove the companies commitment.
