'Big Friend' present help

[DrLucyVanPelt]

Our school has a buddy system, with infants being paired with an older 'Big Friend'. My child's buddy will be finishing Y6 soon. They've been absolutely lovely, and we'd like to get them a small thank you present. Any ideas for a 10/11 year old girl off to high school, budget £10 ish? I've no ideas for this age group! Thanks in advance.

The works have some simple craft sets that look grown up £6-£10
necklaces, cups, bug hotel, trinket box etc

A nice set of pens for big school?
A voucher for say, Claire's? Local Milkshake/bubble tea place? The works?
A chocolate/giant cookie/sweeties gift?

Some fun stationery for secondary school, at that age I was obsessed with gel pens.

I would probably get a lovely card, a small token box chocs and a voucher.

Thanks for the ideas! Will investigate some nice stationery options.
