These are very rare and are very collectible! They are perfect for any NANA fan. I paid over $100 to get these from Japan, so they are not cheap bootlegs. Read the auctions for more details. If you have any questions, feel free to respond here or email me at firstname.lastname@example.org. Thanks!
I also have other manga and jpop items on ebay as well. Check out my list here: http://search.ebay.com/_W0QQfgtpZ1QQfrppZ25QQsassZakanechan81
