Thank you for viewing. This is a set of childcare magazines. There are 12 books in total. [March to December 2011, Pot] - The April issue comes with a new year's birthday chart supplement. - Issues that originally came with CDs still have them included. Some of the CD bags are open, but I never used them because I didn't have a machine to play CDs at the time. - Some issues have been used as references for crafts, etc., so there is some wear and tear, but the contents are still usable. [Play and Environment 0, 1, 2 years old] - Not used much. I have kept them carefully at home. It's been a while since they were released, but would you like them for childcare reference? Please purchase if you understand that they are used items. 97
