2, junior high school students and senior high school students, I think you can send a pen, the more expensive one, which means good; It can be an exquisite notebook, or it can be a manual book between girls.
For college students, boys can give each other jerseys, basketball, tickets for a certain star, or exquisite pens, or books that the other party likes but has never bought. For girls, it is bracelets, lipsticks, various beauty products, or other exquisite items. I think giving gifts depends on the needs of others. You can observe what the other person pays more attention to every day, so that you can have a direction when giving gifts.
