This is a set of 4 clear files. There are two identical clear files of Iso. The Ichiban Kuji clear file also comes with a postcard set. These were received as gifts, and neither the previous owner nor I have opened or used them. However, there are some minor stains on the packaging and some creases on the files themselves, so please refrain from purchasing if you are concerned about this. They will be shipped in simple packaging. Please feel free to ask any questions.
