GREAT FOR HOME SCHOOLERS, COLLECTORS, or the student that just cant get enough science. This was mine in 3rd grade. What a reasonable learning tool compared to the darn textbooks they use today. This set is in nearly unused condition! All training/investigation cards are here, in perfect shape, see pic. The case itself is flawless as can be.witnessed in pics and the fact that it is still stored in original shipping box. When shipped to you, the whole box with set inside will be in yet another box to maintain the remaining integrity of the custom cardboard box. There is no battery pak included but they are.standard issue. The only other thing I believe that could be flawed is the two light bulbs are likely needing replacement.
