What are some good Christmas gift ideas for a religious education teacher to give her 8th grade students?

They are thirteen and I have twelve students. So far I have purchase small little wooden ornaments that I plan to write their names and the year on. I also purchased those crack and glow necklaces, but I am looking for some more items that won’t seem stupid to 13 year olds to throw into a Christmas gift bag for them. Thank you for your help!
