Just putting away my suitcase now from the weekend.
There is still the "use and care" instruction sheet - being the good rule-follower that I am, I read it before recycling it.
It has 8 steps on cleaning and caring for the suitcases, how to store them, etc.
The 8th step, exactly as written: Never allow childrdn to play inside your unzipped luggage as this could damage the locking handle.
