Seems like the boy is into Bottega Veneta period. Aside from his black Bottega wallet which was seen in paparazzi pic when he was shopping at Combini, he has bottega's keychain as well.
The keychain
From Bottega Veneta's japanese website.
Great taste. I like Bottega Veneta in sense that it is glam but not in your face like LV or Burberry. It suits men as well.
¥27,000 is cheaper than what i paid for Sapporo ticket last year anyway.
