Only to people who are insecure weenies and need stickers that announce to the world what they bought.
Helps then justify their purchase and gives them that warm "we're part of the same tribe" feeling when they meet others who also advertise for a product they had to pay for...then again, that's most people...carry on then
Good point- I wouldn't use it on anything but metal (it can haze plastics).I wouldn't use anything with acetate (3M), it can screw stuff up!
