If your girlfriend is a nurse, you can give her some gifts related to her hobbies. For example, if she likes anime, you can give her some cosplay items or books. If she likes sports, you can give her a gym card. The specific gifts still depend on the distance of understanding. I just give some suggestions. If she doesn't have any hobbies or you don't know her very well, I suggest you give her some creative small gifts. The following are recommended:
1. Real dolls: Real dolls made with your lover's photos as models, in addition to realistic images, have the characteristics of permanent preservation. Whether it is a personal fixed model, a multi-person fixed model, or a personal full body customization, or a multi-person full body customization, it is a good gift for her in the distance. I believe that he will be surprised and love it after seeing it.
2. Fashion small mirror, every girl will have a small mirror, either for conceit or for makeup. Although it is an inconspicuous little thing, it can represent a person's taste and a person's interest, so the importance of the mirror is also very high. Buy him a fashionable small mirror so that she can take it out openly and put it back under the envious gaze of others. He will also enjoy such a privilege.
3. Engraved necklace, engrave your attachment to him on the necklace, engrave your thoughts about him on the necklace. Let her wear it around her neck and think of you all the time. This is also a good choice~
I hope my answer can give you some inspiration
