I picked this up at an estate sale and it remains in new condition.  I have 5 more of the quickstudy cards. Copy and paste this to see in our Ebay store

I have checked other sellers auctions and believe my price is among the lowest your will find. I have 100% customer satisfaction and will continue working hard to keep it...

My shipping prices are for the US.  If you have any questions or need more pictures, just drop me an email.
