One of those pillows that looks like an inflating phone battery.
Better idea: 3"*4" Magnetic viewing film, stored in a thoughtfuk card, which is wrapped in a box with 6"*6" thermochromatic film, which is itself is wrapped in a box with a roll of glow in the dark tape, and then given to them with another thoughtful card that holds a gift card to somewhere you think they would like. Basically a nesting set of tiny cool things that all cost about as much as the wrapping paper they are in.
I mean, same here, but if an influencer migrates from Twitter they usually bring their fans with them.
