It's your parents' wedding anniversary. It's rare that you know about it. It's also rare that they still insist on celebrating it every year. It's worth celebrating. As children, you have grown up and can participate in it. It's recommended to choose a more formal gift for such an important day.
Of course, you don't have to spend too much on your parents since you are still a student, so it's better to give them some simple and creative gifts. The key is to show your thoughts.
You can give them a record book to record some major events since your parents met. There are design samples on the website, which are equipped with illustrations, photos, text, cartoons, etc. It is recommended to use the old photos of your parents to customize a real-life cartoon statue. The similarity is very high. It is also very warm to put it in your parents' room. I hope my answer will be helpful to you.
