When consumers purchase travel suitcases:

1、 Firstly, the appearance of the box should be checked, that is, whether the box is upright and the box corners are symmetrical. The suitcase can be placed upright or upside down on the ground,

2、 Check if the suitcase is on all four feet and not skewed, and check if the surface of the suitcase is flat, without scratches or cracks. Pay special attention to the symmetry of the four corners of the suitcase shell (top and bottom).

3、 Open the suitcase and check the box opening. The box openings should match each other, with small gaps and tight seams. The hinges should rotate flexibly without any obstruction, and the clasps should be able to fit, fasten, and open. The box should be firmly adhered, and there should be no jumping or cracking of the textile fabric.

4、 The handle should be securely installed without any looseness. The pull rod should be flexible and have a certain strength. The expansion rod should be properly matched with the fixed rod, and the expansion should not be too large. After the locking button of the pull rod is pressed, it should be able to expand and contract smoothly.

5、 The box wheels should rotate flexibly, and it is best to choose wheels with bearings.

6、 When checking the box lock, you can freely combine several sets of numbers for testing, and open and close normally.
