What to buy tween/teens for under £25 each

[stevienicksismyfairygodmother]

Looking for ideas for girls aged 11,13,15. They're my partners great neices. They don't have any particular sporting hobbies which my daughter did at that age so it was quite easy (horse related stuff). She's now 26, my youngest is a 20yr old man (who's just landed in Bangkok!) and my own great neices are 6 and 3mths and super easy and a joy to buy for.
No idea re this age range. However, I did buy Rio de Janeiro sets for my daughter and partners daughter (22) but now thinking that they might be better suited to two out of these three? And then i would need new ideas for the 22 and 26 year old women - thankfully their main presents are sorted!
Budget £25 each max as we also buy for their parents (my partners nephew and neice)
TIA

My dd age 11 was thrilled with a small set of Posca pens (Rymans have sets on offer usually) and it got her into art in a big way. She’s 14 now and still uses them (asked for some extras when she was 12)

I think Sol de Janerio is perfect for all those girls ages, especially if it’s just the sprays.

My 11 year old would have absolutely zero interest in Sol de Janeiro but she loves her Posca pens!

Personally I’d give the Sol De Janeiro sets to the younger ones and buy a more grown up perfume set for the 20 somethings. Maybe a fragrance discovery set like Floral Street, Jo Malone, or Jo Loves. Floral Street have 15% off your first order so I’ve just ordered 2 discovery sets for £25.50 each
