I made 175 of these. They actually went pretty quickly, but I was covered in glitter by the time I was done

They are magnetic bookmarks.
I also gave everyone a postcard,
and magnet,
I had a few girly party favors leftover that were given to the girls, along with some Halloween pencils, stickers, and tattoos.
The last thing in my baggie was a small Halloween hand sanitizer from Bath & Body Works, probably superfluous, since we had the "cleanest hands in the world" with handi-wipes at every meal.
We got some great stuff. Handmade bookmarks, coasters, a hand painted towel. An incredible handmade bag with our last name embroidered on one side and a Disney ship on the other. Candy, candy, candy (it was Halloween!), card games, tattoos, stickers, pencils, pens, crayons, and on and on!
