Compare to those things sold in amazon.co(USA),
actually, Washouzoku(japanese cloth like kimono) is higher quality in amazon.jp.
There is more information in detail with links in those pictures.
You can buy them with the links. (ref how to buy with amazon.jp)
Calcurating the price in USdollar quickly, divide the yen(orJPY,円,Y with two hoizontal lines) with 100.
I think, buying Japanese anime goods with amazon.jp is the best way,
considering the price and quality.
