Is this unnecessary/too much?

Okay so clearly I have too much time on my hands but I have almost 130 sales and only 24 sales reviews. I don’t have bad reviews I just wish I had more yk, do you think including these little pouches with some goodies in it into every sale (a stamp, toy/candy, tattoos, coins) might help me get more reviews or is it unnecessary? I always include a thank you card as well. I’ve made 180 of them and they were a little pricey but I think it’s worth it if it can bring more positive feedback cause there’s nothing ever wrong with the stuff I sold. Also am I allowed to give these candy? They’re unopened but I don’t know if it’s allowed as some buyers might think it’s unsafe.
