What can I do with a SD card?

Edit: I replaced it with a book

I'm specifically referring to microSD cards here, but I'm too lazy to type that every time and I doubt many people will think of full-sized ones anyway.

I got two 256GB SD cards (Samsung pro plus something) for Christmas, but I can't think of a good use for the second one.
I have a Raspberry Pi, currently with a 32 GB SD card, where I'm gonna put the first one.
My phone has 128 GB of storage, which is already enough for me.
I'm considering putting it in my Nintendo Switch, but it already has a 64GB SD card, which is enough for the 2 non-physical games we have.
I plan on getting a Steam Deck once I can afford it, but that already has a lot of storage.
I don't have a camera or drone or similar.
Selling is not an option.
A refund is technically an option, but I'd rather find a use for it.
