The 28-inch trolley case is a relatively large size. Generally, the length, width and height are about 46*31*70. This is the reference size. Because each manufacturer has different appearances, even the approximate size has a slight length, width and height. The difference, but the difference is not big, it is best to consult the specific size of the store when buying. The 28-inch trolley case can accommodate 15-20 sets of personal clothes, which is suitable for long-term travel. However, if the 28-inch trolley case is full, the weight is relatively large. It is not particularly convenient to carry, and it must be carried by plane. Have to check in.
