The "Derujun Pass Tan" has a slightly wet area on the bottom, but there are no issues with use. The "Concentration Seminar" has a fold in the back. Please check the photos for details. The CD for the "Concentration Seminar" is unused. There are some areas with pen markings and writing. Please be aware of this. I am not using these items, so I would like to pass them on to someone who can use them. Please refrain from purchasing if you are sensitive to used items. If you don't mind the writing, etc., please consider purchasing.
