Incase said:Every New Year, retailers in Japan participate in a tradition knows as fukubukuro, where “lucky bags” are filled with secret items and sold at an attractive discount. This New Year, Incase is proud to support Apple in this very cool tradition by providing a special edition Compact Backpack as the official Apple Lucky Bag, which will secure all the coveted (and secret) Apple and Apple specific merchandise.
Sold exclusively in limited quantities at all Apple Store locations in Japan, each $350 Lucky Bag contains items with a total value of more than double the cost of the bag. Additionally, a few extra special Lucky Bags include a voucher for a new MacBook—a very lucky deal for those fortunate enough to get their hands on one.
