To test bags there is a mechanical arm that picks bags up on drops them on the floor from about half a metre the bag holds a 3 1/2 kilogram weight and is dropped for 4 days.
There is also another piece of lab equipment bombards handbags with ultraviolet rays to test resistance to fading. And another piece that tests zippers by tugging them open and shutting them 5,000 times.
There's even a mechanized mannequin hand, with a Vuitton charm bracelet around its wrist, being shaken vigorously to make sure none of the charms falls off.
Shake and Bake.. that's what we call it in my biz.. lol.
