Curious.. What is your favorite $0.00 Item you have gotten?

I am relatively new to Vine. I will go gold in a few days. Beauty and home products, and costumes are probably my favorite categories. However, I have never found a wig I will turn down since I go to Dragon Con every year I am able and am a big Cosplayer and Halloween is just huge for me, and we go to Ren Faires. However, I was pleasantly surprised when I came across a gem kit, with 60ish different tiny bottles of gems, all bottled up and corked in this nice magnetic box with a chart and everything. That is probably my favorite thing I have gotten so far. **I didn't see anything in the rules saying this wasn't allowed so hopefully it is okay :) And thank you all for being so nice and helpful!
