The gift for a good friend should be more thoughtful. A makeup mirror is a good one. I just saw it online a few days ago. The craftsmanship is very good, very delicate, hollow, and very classy. I was attracted by it when I saw it. Another good gift is meaningful, such as photo albums and crystal display tables. When you are abroad, you can't buy things in China, such as delicious food and some daily necessities.
Sending customized gifts is also very creative. I remember when I was in junior high school, a friend was going abroad, but he didn't have much money at the time, so I gave him a creative little gift. The price was about 100, but my friend liked it very much, a four-leaf clover watch. If you want to give some more practical gifts, as you said, you want her to remember you all the time, you can give her a wallet. Every time she takes out her wallet, she will think of you. This is a better gift. The price is also suitable.
No matter what gift you give her, she will be very happy, because you have your heart in the gift, which is much better than any expensive gift.
