What should I get my best friend for his 14th birthday?

My best friend's birthday is soon (will be 14) and I (f) have no idea what to give him. He lives in another federal state, so the gift should be durable as long as possible (i.e. No chocolate, etc.).

He has no hobbies, but sometimes plays Fortnite.

does anyone have an idea?

A paysafecard maybe…

Amazon voucher? There he can buy films or video games.

Some chocolates can be kept for half a year.
