That depends on your friend's preferences. For example, many students now like to read comics. If he likes it, you can give him a doll made of the characters in his favorite comics; for example, if he likes to play games online, you can give him a set of unlimited mouse and keyboard as a birthday gift. These are very suitable for friends and are more thoughtful.
If you don't know your friend's preferences or don't have time to choose gifts, the gifts are creatively customized, such as chocolates with birthday wishes, and real dolls made from real photos. One-click customization saves a lot of time and energy, which is very convenient.
Finally, you should also pay attention to many gifts that are not suitable for giving, such as flowers and chocolates. However, there is a type of gift that is very suitable, whether it is a classmate of the same sex or a classmate of the opposite sex, that is, school supplies, such as better pens, diaries, etc.
