The tutor system is clean except for the lid. "Let's Play with Songs" has a damaged CD case and folded paper, but everything is included. "Analects of Confucius" is in good condition. "Rhythmical Plaza" has cracks in two CD cases, and there are writings and tears in the workbook and exercise book. There may be other minor stains, but I will not check further than this. I have taken photos of any noticeable stains or damage, but please understand that these are used items that children have used, so there may be stains, etc. Shipping is difficult, so this is a bulk sale.
