The materials were used for about a year and then stored at home, where some pages have been torn by the child. Please check the photos for stains and missing items. There are also some areas with sun damage. The items that are in good condition are mostly unused, so they are clean, but the used items have stains and damage. The pen and card reader have been tested and are working. The DVDs and CDs have not been checked before listing because there are so many. The CDs were used once to rip them to a computer. The DVDs were watched frequently for the earlier numbers, but only a few times for numbers 6 and later. Due to sun damage and damage, and because I want to get rid of them quickly, I am selling them at a significantly reduced price. I plan to sell them to a dealer in two months, so I may delete the listing suddenly. I am open to some price negotiation, so please comment if you are interested.
