What is a good and practical birthday present for girls?

I run a gift shop. Personally, I think giving girls crystals is the first choice. As you said, I think it is most appropriate to send a crystal bracelet. I bought one in Taobao for only 30 yuan, and there are various constellations and styles. The quality and style are good, and the store is also the reputation of Taobao Triple Crown, with more than 60,000 praises. 7 days unconditional return.
