What should I do with 300 rs

I have 300 in Amazon pay , tell me something cool which I can buy from there , i have enough books in my tbr so don't rec that, I have a good pen , a diary , etc

I'm thinking of buying a Rubik's cube ( ik how to solve it ) but I'm bit sceptical about it , idk why it's not exciting me that much

Please give some recs , I'm thinking of any action figure , I like marvel,dc , harry potter and lord of the rings
