But, if you wanna be just a little sneaky and get it yourself, here's my tip.....
Call you local Vuitton boutique in the UK or the main telephone number. Ask for the reference # right over the phone. If you feel any suspicion, tell them you're going to "Japan" and you would like the Reference # b/c you're going to buy it there for a friend. They would infer that it's called something else in Japan and that a reference # would allow them to simply quickly look up the item.
I've done that to 1-866-Vuitton in the US and it work everytime! G'luck
If you were to call LV, giving them that number refers to the item directly. Its like the UPC code of an item, but it's just for LV. Hope that answer your inquiry!
