I think the concept is clever and the patterns are beautiful but I find the way the size is listed misleading. In the general details it says that its free. There was no indication of it being medium until I received it. While I acknowledge the product says that its for Japan use only, There is a chance international consumers will be interested in this item. I think there should be a size button to choose various sizes from small, medium, and large so people get their moneys worth.
