Kenner Sealed Six Million Dollar Man Dip Dots Set

I have a saved search on Ebay for Kenner Dip Dots. I have the Star Wars one. Recently purchased the Strawberry Shortcake one. I really wanted the Bionic Man and Bionic Woman sets. The Bionic Man one popped up one day. It was sealed for under $50. That's a steal. 

Should I open it?
