Presents for a 7 year old girl I've never met

[Chocchip88]

I need help!
I have signed up to do a Christmas gift box for a local child. I have been allocated a 7 year old girl, which is great as I only seem to get to buy for boys recently. However I don't know any 7 year old girls and obviously don't know the girl in question and am a bit stumped as to what they are into these days.

So, questions - would she likely be interested in:
Playmobil
Lego
I also want to get a book, would the David Walliams new Demon Dentist be too old for her?

So far I have a selection box, a make your own perfume set, a make your own lip gloss set and I also want to get some crafty things (not actually bought anything yet, it's all just sitting in my amazon basket so if anything is inappropriate please let me know).
I've got just over £20 left to spend after that.
Any advice greatly appreciated

My DD is nearly 7. Books she loves are Worst Witch, How to Train Your Dragon, the BFG.

Toys: moshi monsters, any cuddly animal, hex bug nano, stickers and notepads and pens, beads.

Dd is 7 and she loves monster high dolls, barbie, playmobil, lego friends, stationery (she loves notebooks stickers pencils shaped rubbers etc), things like handbags bracelets necklaces rings (primark is fab for these) also make up like tinted lip balm. She loves her pack of three owl shaped lip balms from primark.

Where is the best place to get stationery and hair stuff from?

The Demon Dentist is terrifying! My 7 year old girl loves both playmobil and lego, wacky socks, the usborne hard back versions of classics are lovely too.

Op, Paperchase good for stationery, Claire's Accessories for hair stuff

Home Bargains is also good for stationery, (It's also cheap which will help you stretch your budget a bit), also Wilkinsons.

Way too many "alsos" there!

7 year olds are not too old for playmobil.

Hello OP, I don't have anything to add, but could you tell me what scheme this is part of? I would love to do this.
