Hi! I want to gift my boyfriend a custom PCB keychain with his initials on it but I know absolutely nothing about this world. I have no idea what would actually impress someone who's into electronics.

Any advice on where to order, what to add to make it look cool, or what finish/color combo looks best? Keeping it short because I genuinely don't know what I don't know lol. Any help appreciated!
