What’s a unique present I could send my daughter?

My birthdaughter is turning 7 in August. I want to send her something that will be unique and that she can keep for a long time. I sent her something last year too but not for her birthday and it was a package with a gift each for her mom dad and older-by-2-years brother (also adopted). I love this family, our open adoption plan was pics & letters for the 1st 3 years, less pics until age 6 and then nothing until she is 18/wants to contact me. I wish now I had made it more open but at the same time I am very okay with it & I just look forward to knowing her as an adult. I havent sent much of anything to her. I know she is being raised knowing all her bfamilies on both sides love her. I no longer am in contact with her bdad so idk if he or his family contact much. I am also thinking of writing her a letter but dont know what to say or not to say. Her A-Mom says I could never offend them, they will always love me, but i am still very aware of their feelings. Does anyone have any insight? Thanks in advance!
