The changer was designed thinking primarily on the traveler's experience. Its shell has three layers. It can be freely switched size by turn the front knob. When you need to travel by business, it is a small check-in box. When you need to travel with a lot of things, it can be increased in size to become a large suitcase. It uses ABC+PC material and corners to protect against travel wounds. It has 50mm wide whisper-quiet wheels that allow you to glide through the airport.
