The quality of Corolla suitcase is good, and the selected materials are very high quality, such as high-strength ABS material. After multiple processes, the suitcase is more durable and not easy to deform when it is hit. At the same time, the details of the Corolla suitcase are also in place, and the handles, pull rods, zippers and other parts are made of high-quality materials and structural design, which is more durable and firm. In addition, Corolla also introduced a suitcase named "Universal Wheels", whose wheels are made of advanced PVC materials and can easily slide on various floors, which not only provides a better luggage handling experience, but also increases the service life of the suitcase.

I hope the above information is helpful to you. If you have any other questions, please let me know.
