Advent box for teenager

[puginamug]

I received a lovely beauty advent calendar last year.

I've kept the box.

I thought I'd make an advent calendar for DS. He's 12 and fairly unimpressed with everything.

What kinds of things could I put in.

He does quite like toiletries etc but I also need to hold things back for his stocking.

And ideas?

Get him a Pringles one, or a Lynx one? They've gone down well here.

Sweets, popcorn, hot chocolate sachets, coffee sachets, milkshake straw things - edible/drinkable stuff
Vouchers to spend on online games (if he plays any)
Stationery for school - christmassy rubbers, sharpener, pencils/highlighters (don't know how big the drawers are)
Those fidget/ popper toys seem all the rage and you can get small ones although appreciate you may not want plastic tat
Keyring
Phone case (again, not sure if this would fit)
Mini or travel size toiletries
Anything booked / planned for December? You could make a "voucher" for the relevant day saying what you're doing e.g. 'Christmas Market' with a fiver spending money (or whatever the going rate is for a 12yo)

A Christmas gingerbread man.
A mince pie.
Lottery ticket.
£1/£2 coin
Bath bomb. There are themed ones around that he might like eg Star Wars. Lush have some vampire ones at the moment for Halloween.

My dd is 12, her favourite part of advent calendars is the chocolate or sweets. Particularly ones I wouldnt usually buy or unusual ones!

Other things she likes, fidget toys (especially mochi squishy ones), stationery, small mini cans of fizzy, £1 to buy a sweet treat at school canteen or on the way home, mini figures she collects (funko minis). Instructions for a new card game and a pack of cards.

These are all excellent suggestions - thank you.
