reunion

I, together with a number of my high school batchmates are getting together next week. This is the first time we'll be seeing each other after 10 years and everyone's already excited about the mini-reunion. As agreed, everyone will be bringing in food. As one of the main organizers of this event, I have decided to prepare simple souvenirs for all the attendees. I'm expecting a head count of about 25 individuals, all girls, to attend. However, I would need your suggestions on a nice giveaway.I just want the tokens to be simple and not really expensive.
