I have to buy high school graduation presents for six of my friends but I don't know what to buy. High school graduation is a big thing in here Finland but the problem is that I'm quite short with money so I can use max. 20 euros per present (15 pounds/30 dollars). So, do you have any suggestion on what should I get for them? We always give plates and bowls and such as presents to each other but since graduating high school is so important I want to give them something more personal.
