My friend is the one with the sharp eye and likes to hit yard sales. Me, I don't live in an area that has any quality yard sales if you know what I mean. And yes, it was a steal because the entire package was intact! Instructions, both rulers, and the project sheet. Of course both of those are available as PDF's online, along with a video on how the rulers work.
Even the price and where it was purchased from was included in the bag! (so that's how I knew how much they cost!)
