Tumi Luggage

What they say:

"Tumi supply high quality travel cases and luggage items in a wide variety of styles and designed for a wide range of valuable items such as laptops.

They also operate the free Tracer programme for their customers; a unique 20-digit individual product bar code number is printed on a special metal plate that is permanently affixed to Tumi luggage, business cases, casual bags and timepieces. That number, along with the owner's name, address and phone number is entered into their Tracer database when a bag is registered with them. In this way your purchase can easily be tracked if it gets sent to the wrong airport by mistake."
