Gift for enlisting best friend

[Pluto2200]

I know this does not really have anything to do with the service academies but I could not really find much else when searching. My best friend is going to be joining the army after he graduates this year. He means the world to me and has done more for me than anyone else ever has. I want to give him some kind of going away gift or something, however I am unsure of what people are allowed to have on them when they go away to bootcamp/after bootcamp. If he can bring small personal items, what would the best gift to give him be? If I make or buy him a bracelet or necklace or something would that be allowed? Is any kind of jewlery? Anything helps, thanks! At the moment I think I am leaning towards a locket.

Probably wouldn't buy him anything with the intention of him taking it to bootcamp with him but maybe something he can put away until he can safely travel with it. My friends parents bought me a nice pen with my name and branch engraved on it and I still have it to this day. Brings back good memories every time I use it. My mother in law bought me another one complete with engraving when I started my current career and I cherish them both. Best of luck
