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!

What would be a good Christmas gift for volunteer firefighters?

I am President of the Board of Directors for my local volunteer fire department. Every year we have a recognition holiday dinner, and the Board gives something “useful” to the firefighters as a Christmas gift. In the past we’ve done t-shirts, long sleeve t-shirts, Leatherman multi-tools, hoodies, sweatshirts, polos, jackets, etc. What would be a unique, useful gift to give the firefighters that costs between $18 and $25 each?
