As for birthday gifts for boys, I think they must be thoughtful, and they should reflect your concern for him as a little girlfriend.
For long-distance couples, I think the best birthday gifts are couple gifts. A meaningful gift is conducive to communication between you and can make your relationship more stable. For example, this tungsten gold couple ring has a luxurious feeling.
You are still a student, why not give a creative and learning-related gift? This creative pen holder is very good. It looks like a colorful umbrella facing down. There are many bright colors and you can put pens.
No matter how old a boy is, he likes gifts like cars. Here is a red sports car, which is very good. Don't think it is an ordinary decorative car or a toy car. In fact, it is a small vacuum cleaner that can suck dust off the desktop.
