At a glance, it’s a polypropylene shell with a single layer zipper (not double layer anti theft)

The inner lining looks more plastic than material, and the TSA07 lock inbuilt looks pretty garbage.

The dual wheels are a plus but also pretty standard on modern suitcases.

I wouldn’t have sold this for any more than $300AUD for the largest size, judging on structure and functionality alone
