Good return gift for 6-7 year olds.

[CatOnJupiter]

Ideally not one of those variety bags but one decent solid return gift. Also, nothing that is too much work. And is less than £5. Can anyone think of anything? Any ideas would be greatly appreciated!!

What's a return gift?

Top trumps

Like a party bag do you mean? Or in place of a party bag?

We've given:
Fidget toys (you can get really decent ones from The works or B&M)
Books
Fun socks
Among us mini figures.

But mainly I think they just like/expect some cake and sweets.
