Experiment Kit Set (A-TEC Wind Power Generation Assembly Kit & Reagents & pH Test Strips)

I bought these for my child's summer vacation free study project, but they were never used, so I'm selling them.
Both are unopened, but the wind power generation kit was purchased last year, and the indicator was purchased three years ago.

Addendum: I also found a pH test paper strip that has been used a few centimeters, so I'll include that as well.
