The Amazon.co.jp bundle contains the series on BD and DVD in a regular case with a SteelBook and a clear file. The items were wrapped in loose plastic sealed with tape. A piece of plain, brown cardboard was put behind the clear file to protect it against bending.
According to Amazon, a sticker was also included with the first copies sold, most likely as an additional item outside of the plastic wrapping.
