Question about Travelite Basics

Because it's not designed to be stood on.
The castors are only for ease of transport.
It will only be laid flat (on the castors).

From my point of view, this is a bag and not a suitcase. A bag is not standing, a bag is lying on the floor.

Hello
Mine doesn't stand either, even when it's packed full... just always place it against a wall or against an object that is currently available... good luck.
