Looking at your ad, it gives you the impression that the Tag interactive pen comes with it, but it doesn’t. I bought this for my 6 yr. old grandson, and he had already knew all about the book and interactive pen. When he opened it, the first thing he looked for was the pen. Now, I guess, I will have to purchase the pen from someone. You should have at least mentioned in your ad, that the pen was “Not Included.”
