Christmas gifts for brother and friends?

Hi! So I really need help on deciding what to get for my family and friends!

I already know what to get my mom and dad but I have NO IDEA what to get for my older brother.

He is currently 17 years old and likes to play basketball and volleyball. So I was thinking maybe a new basketball? But I'm just trying to get as much ideas and suggestions as I can before I go Christmas shopping this Thursday. Anyways, we aren't that close and honestly he would be happy to receive only money.. But I refuse to.... I want to get him something more meaningful... I asked him what he wanted and he said a new pair of vans.... Sadly I am only 15 and I am using my own money to buy all the gifts... To make it worse, vans are expensive in Korea (where I currently live) and I just don't have the money for it... What should I buy for my brother? That's about $30 or 30,000 won(Korean money). No I will not make him any personalized gifts of anything. He doesn't appreciate those and will most likely end up being dusty. None of those gaming things either... He only plays computer games and I don't even know where to buy games.

Next I need help with what to get my friends.. I recently moved to Korea but all my friends live in America... I want to send them a Christmas letter and maybe a small gift that I can tuck inside with it... No money... Since Korean money is useless in America. No gift cards either... I was thinking may e jewelry? But if I do, it'll have to be silver since most of my friends have sensitive skin... But I'm sending about 10 cards so I don't have the money to buy 10 silver jewelry pieces... Also, the mail could easily get lost along with the jewelry.. Is there anything cheap but flat that I could send? That's meaningful? These could be more personalized since these are my girls.. Thank you! The most helpful will get a 5 star rating~ :D
