Advent calendar for 7 yo boy

[Bobbinsbop]

I am struggle to find an advent calendar for ds. I have got his older sisters make up ones so wanted to get him a fun one to.
He isn't into lego or hot wheels which is mostly what i can find. Budget of about £25.
any recommendations?

My daughter got the little box one.. a few years ago.. like little 24 houses.. and filled them with gifts my Grandson would like.
A fidget toy/ tiny notebook/ pair of socks/ a cat keyring for his back pack.. chocolate coins/ pack of tiny crayons etc .
Pic shows an example.
You can get fancier ones..(.The works/ the range etc

Some more.
Does he like jigsaws?
All the works.
Plus if you filled your own The works is brilliant for tiny gifts.

My grandson is getting a Lego one, or he could get a fidget toy one.

Op said he isn't into legs.

I got a smiggle one for my two boys this year. It was on offer for £15 (I got it on Saturday just fine so probably on offer). It's full of fidgets and I think a bit of stationary

There is a Tom Gates book one, if he is into that - my 7yo is, but that maybe is just because his older brother is. Or a fidget toy one would also be great for my 7yo.

I normally do a fill-your-own with a mix of things.

Smiggle?
