One of the coolest things I saw last week in Japan was a grosgrain book strap at the Beams x Yoshida shop in Daikanyama. The Porter collection is insanely huge and very well done. I consider the brand one of the best in the business. I picked up a tote / backpack hybrid bag in black ballistic nylon at Tokyu Hands for about $145. A steal for the quality and especially good when you factor in that the bag is not available in NYC.
