Gift donations for unknown teens/tweens

[Potatosaladfiend]

Help!
As part of a scheme for, for want of a better word, disadvantaged children, I’ve been asked to donate presents for two 12 year old girls and one 15 year old boy.
Obviously I don’t know them or their interests, and my children are a lot younger so I have no insight into what is appropriate/trendy for these age groups.

Any suggestions please? I would be very grateful for some ideas.

How much do you have to spend?

American or Japanese sweets/snacks
Kawaii cuddly toys/stationery/anything
Fun sheet masks/lip balms/bath bombs
For 15 yo I'd get a voucher - the type that can be spent in lots of different shops
Another option for 15yo - maybe a card game like One night a Werewolf or Throw Throw Burrito

I have the impression that lots of schools now don’t actually have libraries, and that many children own no books of their own. So I’d be inclined to choose books for each of them. Newly published YA fiction for preference.
