Fidget toy ideas for 11yo boy

[3ormorecharacters]

My DD is just finishing Reception and has had the loveliest Y6 buddy. He's really gone above and beyond with her and I'd like to get a nice present for her to give him before he leaves for secondary school. DD says he likes fidget toys. Any ideas along those lines or other things popular with 11yo boys? I'm happy to spend up to £5-10 on it.

The wooden Twist and Lock blocks fidgets are popular or look at Tangles.
There are Infinity spinners, popping fidgets or mini fidget cubes. Your DD probably knows what type he prefers.
Lovely to hear about a positive buddy scheme.
