I can't talk too much about this commercial because I just don't want to spoil the surprise. All I can say is that this is a "love story" type of story, with music of Ryuichi Sakamoto, and that it has a very surprising ending.
The product is Japanese, the agency is GT Tokyo. The title: "Love Distance". Just for the record, the numbers in the middle are in milimiters and 1mm = 0.0393 inches (aprox.)
I am sure that if this was a "western" brand, after seeing this commmercial I would remember the name of the brand. Nice, simple, great idea.
Is not so easy to do a good commercial to advertise the "thin" quality of this product, the same way that it is not easy to advertise the XL version of it with taste.
