It is not appropriate to send cosmetics and expensive jewelry to all girls. It mainly depends on the hobbies of the girls you want to send, and the relationship between you.

If this girl likes reading and playing basketball, then you can also send her some books that she likes. Or a racket. Things are not that expensive, as long as they are what she likes.

Sometimes, if you give a girl something especially expensive, she may not accept it, mainly depending on your relationship. If you are not sure about the relationship, it is impossible for a girl to accept such expensive things as you for no reason, so she will feel that she owes you a lot of favors.

Giving a gift is not about how expensive it is, but about making her happy from the heart and not rejecting you.
