When choosing a suitcase, in order to choose the best suitcase, you need to consider many factors, suitcases with different features will determine your future use. Expandability is an important feature. Generally speaking, choosing expandable luggage is the choice of most people, so why should you choose expandable luggage?
The luggage space needs to be more flexible, and it also needs to have telescopic extra floors. If the capacity of the suitcase can be expanded by about 5cm in an instant, the volume can be increased by about 16%. If you are going on a shopping trip, it is a good choice to bring an expandable suitcase, so you can buy more items and put them in your suitcase.
If you press the case box of a general trolley case with your hand, you will feel a little hard. It is made of hard plastic with a hole in the middle like a honeycomb. Such a case frame will be easily cracked and oxidized after going through hot and cold weather. The inner layer of the expandable trolley case will be compounded with imported EVA foam material, because EVA has properties such as softness, waterproof, good elasticity, and chemical corrosion resistance. At the same time, the 4 sides of the case body are fixed with steel wires, making the case body light and firm, so the suitcase is also lighter, leaving more space for your luggage.
In the north or when it is cold in winter, hard-shell suitcases are easy to crack after being frozen outside, while expandable soft-shell suitcases are not affected by temperature.
The feature of the expandable suitcase is more suitable for places with small storage space, such as student dormitories, work dormitories, etc.
