Whats all the hype about luxury stickers

Recently brands like Anya Hindmarch have been selling luxury leather stickers to decorate bags in a move towards do-it-yourself style embellishment story. I love the idea of personalizing my hand bag but i'm not sure i would want to pay £70 to do it. Having said that i think its a brilliant idea and these seem to be selling like hotcakes so why not! 

The Chinese market and all those billions of people living there just love this kind of kidult kitsch and i'm sure this trend elevated to a luxury level will find its customer base. But, is this just a passing fad or is it something worth keeping? Will my £1500 leather handbag get sticky goo all over it when the adhesive goes bad after 15 years? What do you think?
