What are good things to put in a goody bag for scene girls that are 12 and 13?

my friends are all scene and adorable but i was just wondering what would be good things to put in a goodie bag for girls of the ages 13 and 12 i was thinking glow sticks, gel pens, nail polish, lip gloss, and blow pops. but i want to put something adorable modern not exspensive and awesome in each girls bag but i want it to not be to young and i really want it to be cool ond not super girly frilly and pink, ew. i want it to be a scene item because me and my friends are scene. maybe like cute nerd glasses or something along those lines but not them cuz all my friends have those!! sorry its so spacific but yeah i need to know. p.s. we are having a sleep over if that helps!
