Advent Calendar Filler Ideas for 11 year old DS

[Mumneedstea]

Hi all,

I've got one of those wooden advent calendars that I'm planning to fill myself for DSs 6 and 11.
I don't want to put in sweets everyday as they both are not massive chocolate fans.
I've got a few ideas for DS 6, but nothing for DS 11 that would actually fit into the small drawers of the Advent calendar.

What do you put in yours if you have a DS of similar age?

Thanks!

Bump... Really need some ideas please.

A pound or two pound coin, or a five pound note!
Little lego figure.
Fake tattoes.
Stickers.
Individual hot chocolate sachet.
Marbles.
